Two kinds of parsing methods of XML

XML parsing is the use of more skills in daily projects, whether configuration parameters or data can be stored in an XML file, as well as XML as a format for transmitting data. This article describes two basic parsing methods: XML string parsing and XML file parsing.

XML string parsing

Package Com.discover.parse;import Java.util.iterator;import Org.dom4j.document;import org.dom4j.DocumentException; Import Org.dom4j.documenthelper;import org.dom4j.element;/** * @author Regiment Commander * */public Class Xmlstringparser {public S tatic void Main (string[] args) {String xml = "<?xml version=\" 1.0\ "encoding=\" utf-8\ "?>" + "<ro Ot><student><name>jim</name><age>12</age></student> "+" &LT;STUDENT&GT;&L        T;name>jim</name><age>12</age></student></root> ";            try {Document document = Documenthelper.parsetext (XML);            Element root = Document.getrootelement ();            Iterator stuiterator = root.elementiterator ("student");                while (Stuiterator.hasnext ()) {Element student = (Element) Stuiterator.next ();                String name = Student.elementtexttrim ("name");                String age = Student.elementtexttrim ("Age");System.out.println ("Name:" +name+ ", Age:" +age);        }} catch (Documentexception e) {//TODO auto-generated catch block E.printstacktrace (); }    }}

XML file parsing

Package Com.discover.parse;import Java.io.file;import Java.util.iterator;import org.dom4j.document;import Org.dom4j.documentexception;import Org.dom4j.element;import org.dom4j.io.saxreader;/** * @author Regiment Commander * */public Class Xmlfileparser {/** * @param args */public static void main (string[] args) {String Xmlfilepath = Xm        LFileParser.class.getResource (""). GetPath () + "Stuinfo.xml";        File XMLFile = new file (Xmlfilepath);            if (xmlfile.exists ()) {Saxreader reader = new Saxreader ();                try {Document document = Reader.read (xmlfile);                Element root = Document.getrootelement ();                Iterator stuiterator = root.elementiterator ("student");                    while (Stuiterator.hasnext ()) {Element student = (Element) Stuiterator.next ();                    String name = Student.elementtexttrim ("name");                    String age = Student.elementtexttrim ("Age"); SYstem.out.println ("Name:" +name+ ", Age:" +age); }} catch (Documentexception e) {//TODO auto-generated catch block E.printstack            Trace (); }        }    }}

Both of these parsing methods are implemented using the DOM4J, which can be downloaded on the following website
