grouping multiple xml files in one file
I am trying to merge thousands of article into one xml file. each of the articles is only one line, and they are organized in folders.
for example, folder A has (1.xml, 2.xml, 3.xml...50.xml) and
folder C(has weather51.xml, travel52.xml...etc).
any help/ideas/suggestions/existing stylesheet that handles similar cases would be very helpful.
