dom4j解析xml文件.doc

本文记录怎么用dom4j解析xml文档，第一个例子是简单的解析一层节点，用了一个迭代器 第二个例子是解析两层节点，用了两个迭代器，即迭代器里套用迭代器 例一：Xml文档代码package com;import java.io.File;import java.util.Iterator;import java.util.List;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.Element;import org.dom4j.io.SAXReader;public class ioo public static void main(String args) throws DocumentException SAXReader reader = new SAXReader();Document document = reader.read(new File(D:test1.xml);Element rootElm = document.getRootElement();Element root1Elm = rootElm.element(userlist);List nodes = root1Elm.elements(item);for (Iterator it = nodes.iterator(); it.hasNext();) Element elm = (Element) it.next();System.out.println(index: + elm.attributeValue(index)+ level: + elm.attributeValue(level) + nickname:+ elm.attributeValue(nickname) + country:+ elm.attributeValue(country) + weiwang:+ elm.attributeValue(weiwang);结果例2Xml文档代码package com;import java.io.File;import java.util.Iterator;import java.util.List;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.Element;import org.dom4j.io.SAXReader;public class ioo public static void main(String args) throws DocumentException SAXReader reader = new SAXReader();Document document = reader.read(new File(D:test1.xml);Element rootElm = document.getRootElement();List nodes1 = rootElm.elements(userlist);for (Iterator it1 = nodes1.iterator(); it1.hasNext();) Element elm1 = (Element) it1.next();List nodes2 = elm1.elements(item);for (Iterator it2 = nodes2.iterator(); it2.hasNext();) Element elm2 = (Element) it2.next();System.out.println(index: + elm2.attributeValue(index)+ level: + elm2.attributeValue(level)+ nickname: + elm2.attributeValue(nickname)+ count
