[Petal] [HELP] Anybody has experience with parsing?

Don't worry, I'll try to rip as much code as I can from your patch.
Seems to be the only thing I end up doing on Petal those days: ripping
and playing with patches and adding / running tests.

It's actually quite cool :)

*cough* Fergal _is_ making a lot of progress, I'm just starting to
understand Parse::RecDescent and he contributes an entirely alternative
code generator. Now how am I supposed to feel? Happy I guess :)

Mhhhhh... not so sure about that. I would rather move on the libXML /
SAX side of things than Template Toolkit. Basically I think in the long
run Petal should be able to:

* use SAX events as input to that it can parse just about anything,
* generate completely standalone Perl code
* this Perl code should generate SAX events too

I think it should also:

* be more extensible. It is already in a large extent but it would be
nice to turn the petal:<something> attributes into one module per
attribute type.

* have an augmented but also backwards compatible TALES syntax. Well,
apart from the escaping mechanism that is.


Maybe It's a bit ambitious?
Anyone has got an extra life to spare please? :-)

Cheers,
