I suppose you are talking about XPA's parser, right? It has quite some 
limitations among them the ones named by you. Just use any SAX parser 
you like and you should be ok :)

XPA is for Java only, that's right. Again, it seems you mistake XPA for 
its integrated parser. This parser is only a part of XPA. This parser 
could be ported to C++ with little effort, that's right. Porting XPA to 
C++ is somewhat harder. I am not shure if it is worth it. I would 
propose to use a simple C++ SAX or DOM parser instead of XPA. XPA is 
especially suited for *complicated* transformations or imports.

Thanks for the interest and cheers :)
