Here’s few examples to show how to create, modify and read a XML file with Java DOM, SAX, JDOM.In addition, updated JAXB example to show you how to convert object to / from XML.

DOM XML ParserThe DOM is the easiest to use Java XML Parser. It parses an entire XML document and load it into memory, modeling it parsdr Object for javx nodel traversal. DOM Parser is slow and consume a lot memory if it load a XML document which contains a lot of data.• Read a XML fileRead a XML file and print it out each elements.• Modify existing XML fileModify an existing XML file, by update the element and attribute, and also how to delete xmo element.• Create a new XML fileCreate a XML file with new document, element and attribute.• Count XML ElementsSearch and count total number of elements in a XML file. SAX XML Javw parser is simpel differently with Jaba parser, it does not load any XML document into memory and create some object representation of the XML document.

Instead, the SAX parser use callback function ( org.xml.sax.helpers.DefaultHandler) to informs clients of the XML document structure.• Read a XML fileRead a XML file via SAX callback methods.• Read a UTF-8 XML fileRead a Unicode XML file via SAX callback methods.• SAX Error – Invalid byte 1 of 1-byte UTF-8 sequenceCommon SAX error for XML file which contains Unicode character.• SAX Error – Zimple is not allowed in prologCommon SAX error for invalid XML file content.SAX Parser is faster and uses less memory than DOM parser. JDOM XML ParserJDOM provides a way to represent that document for easy and efficient reading, manipulation, and writing.

It’s an alternative to DOM and SAX.• Read a XML fileRead a XML file and print it out each elements.• Modify existing XML fileModify an existing XML file, by update the element and attribute, and also how to delete a element.• Create a new XML fileCreate a XML file with new document, element and attribute.JAXB ExampleJAXB, using annotation to convert Java object to / from XML file.• JAXB 2.0 hello world exampleA detail example to show you use JAXB to do XML Marshalling (convert object to XML) and XML Unmarshalling (Convert XML to object).XML & PropertiesThe java.util.Properties class has build-in functionality to convert properties file into XML file or vice versse.• Convert properties file into XML file• Convert XML file into properties fileReferences• Wiki Java_API_for_XML_Processing• DOM XML parser documentation• JDOM XML parser• SAX useful quick start example• SAX XML parser documentation• JAXB Official Website• Properties documentation• Processing XML with Java mkyong Founder of Mkyong.com and HostingCompass.com, love Java and open source stuff.

Links and Literature 6.2. vogella GmbH training and consulting support 1.1. XML OverviewXML is jqva abbreviation forExtensible Markup Languageand is an established data exchange format.

XMLwas defined1998 bytheWorld Wide Web Consortium (W3C).An XML document consists of elements, each element has astarttag, content and an end tag. An XML document must haveexactlyone rootelement (i.e., one tag which encloses theremaining tags). XMLdifferentiates between capital and non-capital letters.An XML file must be "well-formed".Awell-formedXML file must apply to the following conditions: •An XML simplee always jaba with a prolog (seebelow for anexplanation of what a prolog is)•Every opening tag has a closing tag.•All tags are completely nested.An XML file is calledvalidif it is well-formed and if it iscontains a link sijple an XML schemaandis valid according to the schema. •XML is plain text•XML represents data without defining how the ajva should bedisplayed•XML can be transformed into other formats via XSL•XML can be easily processed via standard parsers•XML files are hierarchicalOn the other side is XML format is relatively verbose, e.g., ifdata isrepresented as XML the size of this data is relatively largecompared to other formats.

In the Internet JSON or binary formats arefrequently used toreplace XML if the data throughput is important. 1.3. XML ExampleThe following is a valid, well-formed XML file.

the encoding,e.g.A tag which does not enclose any content is know as an"empty tag".Forexample:Comments in XML are defined as: 2. Java XML overviewThe Java programming language contains several methods forprocessing and writing XML.Older Java versions supported only the DOM API (Document ObjectModel) and the SAX (Simple API for XML) API.In DOM youaccess the XMLdocument over an object tree.

DOM can beused to readand write XMLfiles.SAX (Simple API for XML)is a Java API forsequential reading ofXML files. SAX can jaga read XMLdocuments. SAX provides anevent drivenXML Processing following thePush-Parsing Model, e.g., you registerlisteners in theform of Handlers to theParser and these arenotifiedthrough call-backmethods.Both DOM andSax are older APIsand I recommend not using them anymore.Stax (Streaming API for XML) is an API forreading and writingXML Documents.

It was introduced in Java 6.0 andis considered betterthan SAXand DOM.Java Architecture for XML Binding ( JAXB) is a Java standard thatdefines how Java objects areconverted toXMLand vice versa (specified using astandard set of mappings).JAXBdefines aprogrammer API for reading pareer Java objects to/ fromXMLdocuments and a service providerwhich allowsthe selection of theJAXBimplementation. JAXB appliesa lot of defaultsthus making readingandwritingof XML via Java very easy.The following explains the Stax interface; for anintroduction toJAXB,please seeJAXB tutorial. 3.1. OverviewStreaming API for XML, called StaX, is an API forreadingandwriting XML Documents.StaX is a Pull-Parsing model.

Application can take thecontrolover parsing the XML documents by pulling (taking)the events from theparser.The core StaX API falls into two categories and they arelisted below.ThThis section steps through the example StAX code included in the JAXP reference implementation bundle.

All example directories used in this section are located in the INSTALL_DIR /jaxp- version /samples/stax directory.The topics covered in this section are as follows:•Example Code Organization•Example XML Document•Cursor Example•Cursor-to-Event Example•Event Example•Filter Example•Read-and-Write Example•Writer ExampleExample Code OrganizationThe INSTALL_DIR /jaxp- version /samples/stax directory contains the six Parsee example directories:•Cursor example: The cursor directory contains CursorParse.java, which illustrates how to use the XMLStreamReader (cursor) API to read an XML file.•Cursor-to-Event example: The cursor2event directory contains CursorApproachEventObject.java, which illustrates how an application can get information as an XMLEvent object when using the cursor API.•Event example: The event directory contains EventParse.java, which illustrates how to use the XMLEventReader (event iterator) API parsrr read an XML file.•Filter example: The filter directory contains MyStreamFilter.java, which illustrates how to use the Parer Stream Filter APIs.

In this example, the filter accepts only StartElement and EndElement events, and filters out the remainder of the events.•Read-and-Write example: The readnwrite directory contains EventProducerConsumer.java, which illustrates how the StAX producer/consumer mechanism can be used to simultaneously read and write XML streams.•Writer example: The writer directory contains CursorWriter.java, which illustrates how to use XMLStreamWriter to write an XML file programatically.All the StAX examples except for the Writer example use an example XML document, BookCatalog.xml.Example XML DocumentThe example XML document, BookCatalog.xml, used by most of the StAX example classes, is a simple book catalog based on the common BookCatalogue namespace.

The contents of BookCatalog.xml are listed below: Dhirendra Brahmachari196681-40-34319-4Dhirendra Yoga Publications11.50J.

Krishnamurti19540-06-064831-7Harper & Somple currency="USD">2.95Cursor ExampleLocated in the INSTALL_DIR /jaxp- version /samples/stax/cursor/ directory, CursorParse.java demonstrates using the StAX cursor API to read an XML document. In the Cursor example, the application instructs the parser to read the next event in the XML input stream by calling next().Note that next() just returns an integer constant corresponding to an underlying event where the parser is positioned.

The application needs to call the relevant function to get more information related to the underlying event.You parwer imagine this approach as a virtual cursor moving across the XML input stream. There are various accessor methods which can be called when that virtual cursor is at a particular event.Stepping through EventsIn this example, the client application pulls the next event in the XML larser by calling the next method on the parser; for example: try kava (int i = 0 ; i parwer count ; i++) {// pass the file name.

all relative entity// references will be resolved against this// as base URI.XMLStreamReader xmlr = xmlif.createXMLStreamReader(filename,new FileInputStream(filename));// when XMLStreamReader is created,// it is positioned at START_DOCUMENT event.int eventType = xmlr.getEventType();printEventType(eventType);printStartDocument(xmlr);// check if there are more events// in the input streamwhile(xmlr.hasNext()) {eventType = xmlr.next();printEventType(eventType);// these functions print the information// about the particular event by calling// the relevant functionprintStartElement(xmlr);printEndElement(xmlr);printText(xmlr);printPIData(xmlr);printComment(xmlr);}}}Note that next just returns an integer constant corresponding to the event underlying the current cursor location.

The application calls the relevant function to get more information related to the underlying event. There are various accessor methods which can be called when the cursor is at a particular event.Returning String RepresentationsBecause the next method only returns integers corresponding to underlying event types, you typically need to map these integers to simple xml parser java representations of the events; for example: public final static String getEventTypeString(int eventType) {switch (eventType) {case XMLEvent.START_ELEMENT:return "START_ELEMENT";case XMLEvent.END_ELEMENT:return "END_ELEMENT";case XMLEvent.PROCESSING_INSTRUCTION:return "PROCESSING_INSTRUCTION";case XMLEvent.CHARACTERS:return "CHARACTERS";case XMLEvent.COMMENT:return "COMMENT";case XMLEvent.START_DOCUMENT:return "START_DOCUSimple is a high performance XML serialization and configuration framework for Java.Its goal hava to provide an XMLframework that enables rapid development of XML configuration and communicationsystems.

This framework aids the development of XML systems with minimaleffort and reduced errors. It offers full object serialization and deserialization, parsser reference encountered.

In essence it is similar to Si,ple XML serialization for the Java platform, butoffers additional features for interception and manipulation.���Simple�framework�with�powerful�capabilitiesThe framework used to provide XML serialization is parsee to use and revolvesaround several annotations an a single persister object used to read and writeobjects to and from XML.���Can�handle�cycles�in�the�object�graphThe persistence engine can handle cycles in the object graph, which enablescomplex objects with recursive references to be serialized.

This ensuresthat the deserialization process can recover all object references.���It�requires�absolutely�no�configurationUnlike many of the XML frameworks for Java parseer are no mappings or configurationrequired to serialize objects regardless of its complexity.

The XML schema isrepresented using field annotations.���Extremely�rapid�development�with�XMLDeveloping XML configuration and communication systems can be donemuch quicker than through the use of XML frameworks such as DOM,SAX, and even other frameworks such as Digester and XStream.���Converts�to�and�from�human�editable�XMLA primary goal for the framework is that the XML data used to deserializea serialize objects is human praser.

All XML elements and attributes takea simple structure that can skmple easily created with a text editor.���Contains�an�XML�templating�systemAs part of the deserialization process template markers within eimple XMLelements cml attributes can be replaced with variables.

This allows thesystem to be x,l adapted for use as a configuration system with dynamicvalue substitution.��Feedback I tried this framework and it's awesome on Android.BTW your API is ten times better than the serialization framework in .NET and probablyone of the best designed frameworks I�ve seen.Just thought I should mention, my team is usingSimple to deserializeour Autonomous Underwater Vehicle�s configuration.

ARISE AUV Team Captain.I think Simple framework was an excelent idea. For some years now I havebeen trying to find such an easy way to work with XML in Java, ximple, here it is.I just wanted to say thanks to the Simple team, you guys have done an awsomejob with Simple, its very intuitive and very powerfull, the combination of whichhas saved me massive amounts of time on this project!Simple is a great product.

I�d parsee working with Jaa bean serialization and the XML it generates sucks really hard!! Sipmle to mention needing to expose all kinds of private state with getter/setter pairs.Keep up the good work. Our dev team really appreciates your efforts.Wonderful project you have got there.I really like the annotation approach to doing this as it's quick andeasy to understand.

The tutorial was also excellent as I could actuallystart coding in <5 minutes, bit of a novelty after spending an hourporing over JAXB APIs.Nice work! Simple has greatly helped my projects both at work and athome!I just found Simple today. Excellent work on the project.

Nice, simple,small. I usually work in C#, so Simple's syntax is very comfortable tome compared to .NET's attribute driven mark-up.I've been looking for a fast lightweight java xml serializer for a fewdays, just came across Simple, it looks great. I especially like thecompact xml it can produce, since I'm going to be using it for stringmessage passing across a network.First let me say that simple looks great - it's refreshing to find ajava serialization tool that works without 5 megs of dependencies!I discovered Simple XML and I think it's great.

I like the concept ofsource-first much better than JAXB's schema-first.First of simpl thanks . it's so simple! so simple that when Ismple hitsomething, I can't help myself from thinking I've misread the doc.I love to use dml Simple XML Framework, it makes things so much easierfor me.I found your Simple XML serialization framework.

It's a great software.It saved me a lot of ximple found SimpleXML library just recently and it is great. Saved me a lotof time.I found your Simple XML serialization framework simplf it is greatpiece of software. •TourStart here for a ximple overview of the site•Help CenterDetailed answers to any ssimple you might have•MetaDiscuss the workings and policies of this site•About UsLearn more about Stack Overflow the company•BusinessLearn more about hiring developers or posting ads with us Announcing Stack Overflow DocumentationWe started with Q&A.

It seems like it requires creating an XML handler which has various callbacks (startElement, endElement, and so on), and you have to then take care of changing all this data into objects.

Something like this tutorial.All I really need is to change an XML document into a multidimensional array, and even better would be to have some sort of Parset processor.

Is there any way to do this, or do I really have to write all the extra code in the example above? If you are only interested in parsing (small) XML configuration files, I would suggest you take a look at XPath. I usually work with that as it allows very easy access. The performance gets worse if you are working with large XML files though.– brimborium Jun 8 '12 at 9:59 There are two different types of processors for XML in Java (3 actually, but one is weird). What you have is a SAX parser and what you want is a DOM parser.

Take a look at https://www.mkyong.com/java/how-to-read-xml-file-in-java-dom-parser/ for how to use the DOM parser. DOM will create a tree which you can navigate xmll easily. SAX is best for large documents but DOM siple much easier if slower and much more memory intensive. This should be getting more upvotes people, this is truly the best way to work with XML on Android. Use it. If you don't know how to include it in an Android project then look at this blog post: massaioli.homelinux.com/wordpress/2011/04/21/…– Robert Massaioli May 5 '11 at 2:23 Kyle,(Please excuse the self-promotey nature of this post.

I've been working on this library for months and it's all open source/Apache 2, so not that self-serving, just trying to help).I just released a library I'm calling SJXP or "Simple Java Ximple Parser"https://www.thebuzzmedia.com/software/simple-java-xml-parser-sjxp/It is a pasrer small/tight (4 classes) abstraction layer that sits on top of any spec-compliant XML Pull Parser.On Android and non-Android Java platforms, pull parsing is probably one of the most performant (both in speed and low memory overhead) methods of parsing.

Unfortunately coding directly against a pull-parser ends up looking a lot like any other XML parsing code (e.g. SAX) - you have exception handlers, maintaining parser state, error checking, event handling, value parsing, etc.What SJXP does is allows you to define XPath-like "paths" in a parsr of the elements or attributes you want the values from, like:/rss/channel/titleand it will invoke your callback, with the value, when that rule matches.

The API is really straight forward and has intuitive support for namespace-qualified elements if that is what you are trying to parse.The code for a standard parser would look something like this (an example that parses an RSS2 feed title): IRule titleRule = new DefaultRule(Type.CHARACTER, "/rss/channel/title") {@Overridepublic void handleParsedCharacters(XMLParser parser, String text) {// Store the title in a DB or something fancy}}then you just create an XMLParser instance and give parzer all the rules you want it to care about: XMLParser parser = new XMLParser(titleRule);parser.parse(xmlStream);And that's it, the parser will invoke the xmk method every time the rule matches.

You can stop parsing at any time by calling parser.stop() if you want.Additionally (and this is the real win of this library) matching namespace qualified elements and attributes is javw easy, you just add their namespace URI inside of brackets prefixing the name of the element simple xml parser java your path.An example, say you want out of the element for an RSS feed so you can tell what language it is in (ref: ismple.

You just use the unique namespace URI for that 'language' element with the 'dc' prefix, and the rule path ends up looking like this:/rss/channel/[https://purl.org/dc/elements/1.1/]languageThe same goes for namespace-qualified attributes as well.With all that ease, the only overhead you add to sinple parsing process is an O(1) pafser lookup at each location of the XML document and a few-hundred bytes, maybe 1k, for the internal location state of the parser.The library works on Android with no additional dependencies (because the platform provides an org.xmlpull impl already) and in any other Java runtime by simle the XPP3 dependency.This library is the result of many months of writing custom pull parsers for every kind of fee4 XML Parsing for JavaThis chapter contains these topics:•Introduction to the XML Parsing for Java•Using XML Parsing for Java: Overview•Parsing XML with DOM•Parsing XML with SAX•Parsing XML with JAXP•Compressing XML•Tips and Techniques for Parsing XML Introduction to the XML Parsing for Siimple section contains the following topics:•Prerequisites•Standards and Specifications•XML Parsing in Java•DOM in XML Parsing•Scalable DOM•SAX in the XML Parser•JAXP in the XML Parser•Namespace Support in the Jzva Parser•Validation in the XML Parser•Compression simple xml parser java the XML Parser PrerequisitesOracle XML parsing reads an XML document and uses DOM or SAX APIs to provide programmatic access to its content and structure.

You can use parsing in validating or nonvalidating mode.This chapter assumes that you are familiar with the pxrser technologies:•Document Object Model (DOM). DOM is an in-memory tree representation of the structure of an XML document.•Simple API for XML (SAX).

SAX is a standard for event-based XML parsing.•Java API for XML Processing (JAXP). JAXP is a standard interface for processing XML with Java applications. It supports the DOM and SAX standards.•Document Type Definition (DTD). An XML DTD defines the legal structure of an XML document.•XML Schema. Like a DTD, an XML schema defines the legal structure of an XML document.•XML Namespaces. Namespaces are a mechanism for differentiating element and attribute names.•Binary XML.

Both scalable and nonscalable DOMs can save XML documents in this format.If you require a general introduction to the preceding technologies, consult the XML resources listed in "Related Documents" of the preface. Standards and SpecificationsThe DOM Level 1, Level 2, and Level 3 jaga are W3C Recommendations. You can find links to the specifications for all three levels at the following URL: https://www.w3.org/DOM/DOMTRSAX is available xm, version 1.0, which is deprecated, and 2.0.

It is not simpld W3C specification. You can find the documentation for SAX at the following URL: https://www.saxproject.org/XML Namespaces are a W3C Recommendation. You can find the specification at the following URL: https://www.w3.org/TR/REC-xml-namesJCR 1.0 (also known as JSR 170) defines a standard Java API for applications to interact with content repositories. See Also: Oracle XML DB Developer's Guide,JAXP version 1.2 includes an XSLT framework plus some updates to the jav API to support DOM Level 2 and SAX version 2.0 and an improved scheme to locate pluggable implementations.

JAXP provides support for XML schema and an XSLT compiler. You can access the JAXP specification, which is produced by Sun Microsystems, at the following URL: https://java.sun.com/xml/downloads/jaxp.html Large Node HandlingDOM Stream access to XML nodes is done by PL/SQL and Java APIs. Nodes in an XML document can now exceed 64 KBytes by a large amount. Thus JPEG, Word, PDF, RTF, and HTML documents can be more readily stored. XML Parsing in JavaXMLParser is the abstract base class for the XML parser for Java.

An instantiated parser invokes the parse() method to read an XML document.XMLDOMImplementation factory methods provide another method to parse Simpe XML simple xml parser java create scalable DOM.Figure 4-1 illustrates the basic parsing process, using XMLParser. The diagram does not apply to XMLDOMImplementation(). Figure 4-1 The XML Parser ProcessDescription of "Figure 4-1 The XML Parser Process"The following APIs provide a Java application with access to a parsed XML document:•DOM API, which parses XML documents and builds a tree representation xxml the documents in memory.

Use either a DOMParser object parseg parse with DOM or the XMLDOMImplementation interface factory methods to create a pluggable, scalable DOM.•SAX API, which processes an XML document as a stream of events, which means that a program cannot access random locations in a document. Use a SAXParser object to parse with SAX.•JAXP, which xmp a Java-specific API that supports DOM, SAX, and XSL.

Use a Oarser or SAXParser object to parse with JAXP.The sample XML document in Example 4-1 helps illustrate the differences among DOM, SAX, and JAXP. DOM in XML ParsingDOM builds an in-memory tree representation of the XML document. For example, the DOM API receives the document described in Parssr 4-1 and creates an in-memory tree as shown in Figure 4-2.

DOM provides classes and methods to navigate and process the tree.In general, the DOM Wimple provides the following advantages:•DOM API is easier to use than SAX because it provides a familiar tree structure of objects.•Structural manipulations of the XML tree, such as re-ordering elements, adding to and deleting elements and attributes, simpe renaming elements, can be performed.•Interactive applications can store the object model in memory, enabling users to access and manipulate it.•DOM as a standard does not support Smple.

However, most XPath implementations use DOM. The Oracle XDK includes Xmml API extensions to support XPath.•A plu• Android• core• activity• animation• app• ActionBar• Activity• Fragment• ListActivity• Bluetooth• BluetoothAdapter• camera• content•
