Hi Evgeniy,
Can you please let us know where will you direct the output of the text function.
Secondly even if you are able to direct the output to entire xml of target, there is another issue.
How many node names you need to compare to with entire source XML. As per first post by Ramesh, there are lot many fields like this.
I do not mean to offend you in any way just curious to know.
Regards
Anupam
