Strange results in xml parsing

i have a very simple xml
<?xml version="1.0"?>
<root>
<control>
<element>name</element>
<elementtype>input</elementtype>
<subtype>text</subtype>
</control>
</root>

And a simple parsing code using the org.w3c.dom package(1.4.2 java):
//get a nodelist formed by getelementbytagname("control")
NodeList list=utils.getList(filter);

System.out.println(list.getLength());//prints 1 which is correct

for(int i=0;i<list.getLength(); i++) {
Element node = (Element)list.item(i);
System.out.println("Name=>" + node.getTagName());//prints 'control' which is correct

NodeList childlist=node.getChildNodes();

System.out.println(childlist.getLength());//print 7!!!

}

Why is the last iteration printing 7?
How do i print out the name and value of the children of 'control'?

Ranadhir Nag,

You've posted your XML parsing question in the JSP forum.
I'll move it to our XML forum for you.

Because there are 7 nodes - you forgot the TEXT type nodes containing crlf between the Elements.

I suggest you go to Sun's DOM tutorial for ideas on getting the name and value of DOM nodes.
