Investigate the use of document('foo.xml') to get the root node of an
arbitrary XML document, when given the document's URI. You can put the URIs in
elements in a separate document and iterate over them with for-each. Note that
every document you access via document() will be loaded into memory and most
likely kept there for the duration of processing, so XSLT is not ideal for
this job if you have many or large XML docs. You should look into writing a
SAX application. It'll be much faster and more efficient, but you will have to
get your hands dirty with lower-level programming.
