[XML-SIG] how to obtain Byte offset from the Locator...

[Greg Wolff]

I have a copy of expat for my C++ code but I have found that I don't
have a copy of the driver for expat for the Python code.  I have the
xmlproc code and it works just fine, but it doesn't have byte offset as
far as I can tell.  (My first cursory look at the code suggests that it
would be better to ask you'all for help rather than try to hack it...)

Which file on the xml-sig download page has the Python Expat code in
it?  I have tried to download a pyexpat file but the link was broken
last night when I tried it.  If I can get the pyexpat code I'll hack it
as Lars M. suggests below (Thanks!).

Also, is there any chance of trying to work with the SAX 2.0 Python
code?

Thanks for the help.
