Hello All,
I have some queries related to one task i am doing in our code

I will demonstarte with some pseudo xml files as it will not be possible for me to paste exact code fragment

Lets say i have A.xml
<?xml version......?>
<a>
<B>
<c>Some data</c>
</B>
<B>
<c>Another data</c>
</B>

<d>
<x>hi to all</x>
</d>
</a>

Now what i want to do is extract all the tags with <B> ffrom this xml(A.xml)& want to append in another xml Say B.xml as a child of root tag say note
something like this
B.xml (Before OPeration)
<?xml ver...........?>
<note>

</note>



================================
I need this kind of B.xml after processing
B.xml (after OPeration )
<?xml ver...........?>
<note>
<B>
<c>Some additionaldata</c>
</B>
<B>
<c>Another additional data</c>
</B>

</note>

I am using XPath for finding out all B's element from A.xml
with expression like /a/B...getting it as a NodeList
Now my question is how to add this data in another XML(B.xml) at specified place.

Thanks for your patience
Regards

Shrinivas
