xml文件简单读取，循环遍历

xml文件的简单读取出来生成dom4j.document对象树，循环遍历获取节点

例子：

import java.util.iterator;

import org.dom4j.document;
import org.dom4j.documentexception;
import org.dom4j.element;
import org.dom4j.io.saxreader;

public class dom4jtext {

    /**
     * @param args
     */
    public static void main(string[] args) {
        
        try {
            //创建解析器
            saxreader saxreader=new saxreader();
            //通过解析器将xml读取到内存中，生成对象树
            document document=saxreader.read("conf/student.xml");
            //获取根节点
            element root=document.getrootelement();
            //遍历根节点
            for(iterator<element> rootlter=root.elementiterator();rootlter.hasnext();){
                element student=rootlter.next();
                for(iterator<element> innerlter=student.elementiterator();innerlter.hasnext();){
                    element innerelt=innerlter.next();
                    string name=innerelt.getname();
                    string value=innerelt.getstringvalue();
                    system.out.println("name========="+name+"======value========="+value);
                }
                system.out.println("-------------------------------");
            }
        } catch (exception e) {
            // todo auto-generated catch block
            e.printstacktrace();
        }
    }

}

程序用到xml:

<?xml version="1.0" encoding="utf-8"?>
<students>
    <student>
        <name>张三</name>
        <age>11</age>
        <adress>浙江省是打发斯蒂芬二人11</adress>
    </student>
    <student>
        <name>李四</name>
        <age>22</age>
        <adress>浙江省是打发斯蒂芬二人22</adress>
    </student>
    <student>
        <name>王二麻子</name>
        <age>33</age>
        <adress>浙江省是打发斯蒂芬二人33</adress>
    </student>
</students>
