http://cttl.sourceforge.net/ may be of value here

http://itpp.sourceforge.net/ may help with some of the math.
http://www.osl.iu.edu/research/mtl/ for some matrix, linear algebra stuff

http://itpp.sourceforge.net/ may be useful for xml

I've used http://homepage.mac.com/pauljlucas/software/html_tree/ to parse
html.  It has a built in element iterator, but look at the code to confirm,
as there is only a prefix ++ rather than prefix ++.

Some stuff in http://swishplusplus.sourceforge.net/ may be useful for text
mining.
