Java Parsing Multilevel XML

A single child node object is obtained under the parent node.
Element memberelm=root.element ("member"); "Member" is a section roll call

Gets the parent node to traverse all child nodes named "member". List nodes = rootelm.elements ("member");
for (Iterator it = Nodes.iterator (); It.hasnext ();) {
Element elm = (Element) It.next ();
Do something

}

Iterate through all the properties of a node
Element root=document.getrootelement ();
For (iterator It=root.attributeiterator (); It.hasnext ();) {
attribute attribute = (attribute) it.next ();
String Text=attribute.gettext ();
System.out.println (text);
}

XML file: XML version = "1.0" encoding = "GBK"?>
< doc >
< Person id = "1" sex = "M" >
< name >zhangsan </name >
< age >32 </age >
< adds >
< add code = "Home" >home add </Add >
< add code = "com" >com add </Add >
</adds >
</person >
< Person id = "2" sex = "W" >
< name >lisi </name >
< age >22 </age >
< adds >
< add ID = "" id = "" "Code =" Home ">home add </Add >
< add id = "" "id =" "code =" com ">com add </Add >
< add id = "in" code = "com" >com add </Add >
