Merging xml files

Dear rooters,
I have xml files with esd root files (from alien find command).
I would like to merge them to only one xml file, how can I do it in a safety way?

Thank you very much for any kind of help.
Cheers.

Hi,

It sounds like those xml file are experiment specific files contains a file of ROOT files. I recommend you check with your experiment if they have any such tool. Otherwise it is also possible that the format is simple enough that any xml tool might be able to do what you need.
