分享xml递归解析
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<resource name="level1" >
<resource name="level2" >
<resource name="level3" >
</resource>
</resource>
</resource>
<resource name="text1" >
</resources>
遍历这个xml 要得到如下效果：
public class Xml2 {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub 10jq
Node root=new Node();
root.text="";
root.children=new ArrayList<Node>();
Node level1=new Node();
level1.text="level1";
level1.children=new ArrayList<Node>();
Node level2=new Node();
level2.text="level2";
level2.children=new ArrayList<Node>();
Node level3=new Node();
level3.text="level3";
level3.children=new ArrayList<Node>();
level2.children.add(level3);
level1.children.add(level2);
Node text1=new Node();
text1.text="level3";
text1.children=new ArrayList<Node>();
root.children.add(text1);
}
}
class Node{
public String text;
public List children;
}
要通过遍历xml自动获得这个list
