    Please see Concatenating XML files, I found the answers quite helpful.

    It won't get you there to 100%, but it'll show you how similar things are done with various XML modules.

    My CPAN search for xml merge revealed a module XML::Merge. Maybe that can be helpful in your case?

    moritzs suggestion apart (I haven't yet been to have a look), it looks (from slightly sparse evidence) like you want a simple merge of 2 (or maybe more) XML files, so why not ...
    1. Read each file into its own hash (using XMLin() from XML::Simple,
    2. Merge all the input hashes
    3. Finally, write the resultant hash using XMLout() (again from XML::Simple).
    Assuming, of course, that the combined size of the input XML files isn't huge (and thus likely to cause the process to run out of memory).

    A user level that continues to overstate my experience :-))
