Thanks George. I just returned from the bookstore and was looking at an XSLT solution in one of the books there. I want to import the data into the DB as regular data, not as XML. I'll look into Saxon and TagSoup as well as the perl module you mentioned. As far as this being outside the scope of the list, I wasn't sure whether or not there were postgres modules to deal with this. Thanks for pointing me to possible solutions.
