java mapping lookup and add or modify source xml file

Om


Some times you are supposed to lookup other systems 
1) to get more information efficiently by query other system
2)  and modify the lookup content in our required manner

then, lookup other systems, get the content.
( to fetch content in xml files, we need to do various operations)
instead of that.

Append the source xml and lookup xml file together.
( generate target xml file using graphical mapping ).

Merging two xml files in java mapping.
( later planning to generate my target required xml file using graphical mapping.

Code to merge two xml files;
