dom4j简单的XML文件遍历 demo
随便找一个简单的xml文件，存放进自己的项目中
data.xml
<?xml version="1.0" encoding="UTF-8"?><monitorCenter id="0" name="根"> <area id="108405" name="1" > <concentrator id="108409" name="11" > <nodeContrl id="108429" uid="111111111112" name="111" ></nodeContrl> <nodeContrl id="108425" uid="111111111111" name="112" ></nodeContrl> <groupMaintain id="108421" groupId="2" name="113"></groupMaintain> <groupMaintain id="108417" groupId="1" name="114" > <nodeContrl id="108433" uid="222222222222" name="1141" ></nodeContrl> <groupMaintain id="108437" groupId="3" name="1142" > <nodeContrl id="108445" uid="333333333333" name="11421" ></nodeContrl> <groupMaintain id="108441" groupId="4" name="11422" ></groupMaintain> </groupMaintain> </groupMaintain> </concentrator> <concentrator id="108413" name="12" ></concentrator> </area> <area id="108449" name="2" ></area></monitorCenter>?

java简单遍历
package com.royal.client;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 Dom4jClient {private static String filePath = "src/main/java/com/royal/asset/data.xml";public static void main(String args[]) {SAXReader reader = new SAXReader();try {//读取xml文档Document document = reader.read(filePath);//得到xml文档根节点元素Element root = document.getRootElement();//获取根节点的子节点//List<Element> elementList = root.elements();////得到子节点之后就是自由发挥的时候了，比如遍历子节点得到子节点的结点名称和节点的值//Iterator<Element> it = elementList.iterator();//Element element = null;//while(it.hasNext()){//element = it.next();//System.out.println(element.attributeValue("name"));//childElements(element);//}childElements(root,1);} catch (DocumentException e) {e.printStackTrace();}}public static void childElements(Element element, int level){String preStr = "";for(int i = 1; i <= level; i++){preStr += "------";}List<Element> elementList = element.elements();Iterator<Element> it = elementList.iterator();Element e = null;while(it.hasNext()){e = it.next();System.out.println(level + preStr + e.attributeValue("name"));childElements(e,level + 1);}}}?
别忘了导入dom4j jar包.
