Get problem in loading the xml code

Question

Hi all,
I have got one problem in program. </method >not get generates after method block.
I want output like this:
<?xml version="1.0" encoding="UTF-8"?>
<interface>
---<name>the name of package</name>
---<className>The name of class</className>
----<methods>
---------<name>the name of the method</name>
---------<returnType>the return type of the method</returnType>
-----</methods>
----<methods>
---------<name>the name of the method22</name>
---------<returnType>the return type of the method22</returnType>
---------</methods>
</interface>
But the output comes like:
<?xml version="1.0" encoding="UTF-8"?>
<interface>
---<name>the name of package</name>
---<className>The name of class</className>
----<methods>
---------<name>the name of the method</name>
---------<returnType>the return type of the method</returnType>
---------<name>the name of the method22</name>
---------<returnType>the return type of the method22</returnType>
---------</methods>
</interface>

Please help me.
Thanks

Replace the following line:methodnode.appendChild(docfrag);with these lines:Node methodnode2 = packageDoc.createElement("methods");
packageDoc.getDocumentElement().appendChild(methodnode2);
methodnode2.appendChild(docfrag);The problem was that you omitted to create a new <methods> element for the document fragment to be inserted in, so it got inserted in the original <methods> element.
