[xmljs-users] SAX: Entity Resolution/Skipping

[Jim C. <ji...@ps...>]

Hi everyone,

I've recently did a straight port of the XML for <SCRIPT> 3.0's
SAX parser to Flash MX 2004's Actionscript 2.0 (essentially
ECMAScript Draft 4) to bootstrap the development of an open-
source, standards-compliant DOM that I'm working on.  See:

   http://www.psalterego.com/flash/sax.html

In using the SAX parser, I've run into an issue with resolving
general entities that aren't specified by the XML recommendation,
e.g. Latin-1 XHTML entities like &eacute; and such.  At present,
the XML for <SCRIPT> SAX parser throws an "unknown entity" error
and exits.

As the SAX parser isn't validating and doesn't implement the
SAX2 entityResolver interface, I would like to suggest that a
skippedEntity event be added that would be fired (if defined)
instead of throwing a fatal unknown entity error to allow the
SAX parser to play well with XML files that use entities other
than predefined entities given in the XML specification:

   http://www.w3.org/TR/2004/REC-xml-20040204/#sec-predefined-ent

Say, implementing a skippedEntity event like the one in SAX2's
contentHandler interface.  I could provide a patch against the
current code to implement this if there's interest.  Thoughts?

Regards,
Jim
