Concatenating many XML files

Hi ...

My program accesses 50 xml files one at a time, uses JAXP API and DOM parser to update each and puts the updated DOM into a new XML file. So, I will be left with 50 updated xml files. Its fine till now...

But what I want to accomplish is to have a SINGLE xml file as output instead of 50 different xml files.

i tried to append one dom to an other as a child element but it didnt work as we cannot append DOMs.

Is there any way to concatenate these XML files?
Any suggestion is greatly appreciated!

Thanks.

As I remember in VS.NET you can import DOM node, maybe this will help you..

Thanks mikefmi for your reply.
I tried importNode() methos in Java and it worked!!!!

Thanks again!
