XML Size

[my_questions]

Hi,

I am writing to a XML file using Java and saving the XML and I have
to maintain different XMLs for each given Root Node.

That is I have to maintain 10 XMLs if I have 10 different root
nodes, that is not a problem.

My problem, is that when these XMLs will grow in size it will be
difficult to maintain them. I cant fix them on number of records, what
should be the best way to maintain these.

Thanks in advance.
