Yuck? WTF? Its beautiful! Maybe I should explain some more.
I followed the same links you described and realized that without some
hacking in and around XMLScanner getting the BinInputStream from the
ReaderMgr is a no go. BTW, getting at XMLScanner from a parser would be
real handy for lots of these kind of reasons.
BUT, if you write your own file/mem InputSource that caches away its
BinInputStream you can get at it from you sax event handler:
class cSuperFastMemInputSource : public MemBufInputSource
{
BinInputStream* MemBufInputSource::makeStream() const
{
if (fMemStream = null)
{
fMemStream = new BinMemInputStream(fSrcBytes, fByteCount,
fCopyBufToStream ? BinMemInputStream::BufOpt_Copy :
inMemInputStream::BufOpt_Reference);
}
return fMemStream;
}
};
Have your SaxEvent handler class:
class mysaxeEvents : public DocumentHandler
{
cSuperFastMemInputSource *fstrm;
mysaxeEvents(cSuperFastMemInputSource *strm)
{
fstrm = strm;
}
virtual void startElement(const XMLCh* const name, AttributeList& attrs)
{
int whereAmI = fstrm->curPos();
}
};
