you might have an easier time w/ SimpleXML for this task; have a look at the
examples:
http://us.php.net/manual/en/simplexml.examples-basic.php
the other thing i find strange about this code is the xml parsing assumes a
similar schema when the source urls are from seemingly totally disparate
domains, and topic .. id guess it sheer coincidence they have overlapping
schemas at all.
