insert node into DOM

[Lingzhi Zhang <lz...@cse.ogi.edu>]

Hi, 

I am using xerces to try to insert xml into the certain node in the DOM
which satisfies some xpath expression. The simple structure of my original
xml is like
<root>
    <A><B>10</B></A>
    <A><B>10</B></A>
</root>

I try to run "insert <A>new</A> //A[B=10]", and my code is like

    NodeIterator i = XPathAPI.selectNodeIterator(contextNode, xPath);
    Node node;
    while((node = i.nextNode()) != null) {
	Node parent = node.getParentNode();
	parent.insertBefore(docFrag, node);
    }

There should be two insertions before each of the <A><B>10</B></A>, 
however, I just got one. It just inserts the <A>new</A> before the first
<A><B>10</B></A>, while not the second. I check my code, it dose call
parent.insertBefore(docFrag, node) twice, which makes me very
confused. Any idea what's wrong? Thanks.

Stephen

PS:
expected result:
<root>
    <A>new</A>
    <A><B>10</B></A>
    <A>new</A>
    <A><B>10</B></A>
</root>

actual result:
<root>
    <A>new</A>
    <A><B>10</B></A>
    <A><B>10</B></A>
</root>
