I haven't yet made offsets available in SAX2, but I plan to do so in
the next release. I was thinking of two possible ways to do this:
- a SAX2 parser property that returns the current offset
- a SAX2 parser property that returns a function that returns the
The first is the least surprising way, but I think the second is
likely to be faster and also more convenient. Opinions on this would
Support for this property will of course be optional, but both expat
and xmlproc will support it, since they both provide the necessary
information. If any other parsers provide it they will also support

With the addition of the byte offset information SAX 2 should cover
your requirements, I assume?
BTW: Thank you for a very interesting post. It's always interesting to
know what people are using this software for.
