Problem cloning Node

Sailesh

Hi eveyone,

I am facing an issue with xml creation.

What I want to do:
Compare an XML file and an Xml DCR file.
If the IDs for the various tags match, update the xml with DCR content
If New ID in DCR append it in XML.

Tried various approach and finally reached this one.

But now I am not able to clone the node and append to the file.

Any help is more then welcome.

Find enclosed the code file and xml file (error.txt)
