David,
I've started porting the serializes to C++ for use with TransforMiiX,
unfortunatly they can't readily be used in Xerces since TransforMiiX and
Xerces use different DOM implementations and SAX interfaces. The W3C
stayed clear of giving C++ bindings, probably due to all the
inconsistencies across platforms with C/C++. At one point Dave Megginson
proposed a C++ SAX interface, but he never made it official and it's not
available from his website. Again it's not an easy task...should I throw
exceptions or not? Should I rely on the STL or not? Most C++ compilers
don't support the STL well.
In anycase I can look into getting something working for Xerces when I
get back from ApacheCon. Hopefully if I do, Assaf will maintain both the
Java and C++ code bases...but I'll have to bribe him I think.
Of course feel free to jump right in and do a direct port for Xerces C
if you are interested in doing so.
