As you know, I had been working on sax and entities some, and in October
submitted a patch to the tracker that partially addressed my ultimate
goal. I was never able to achieve the ultimate goal, but I figured out
quite some time ago one way to handle entity substitutions in SaxParser.
The patch on the tracker did not really make sense without the derived
SaxParser in my unposted example. I just posted a revised patch that
embeds this handling inside SaxParser proper. Note, it uses an empty
dummy Document to perform its magic. In any case, it does work, and it
is worth considering. The nice thing about using the dummy document is
that we leverage the facilities with libxml2 for entity resolution.
Check out the updated patch on the tracker and let me know what you
think.
