Re: [xmljs-users] SAX: Entity Resolution/Skipping

[David J. <dj...@ya...>]

Hi Jim, 

That sounds like it would be a nice addition. In making your patch, could you do the following
please?

* Coordinate with Robert (cc'd on this Email) so that your patch doesn't collide with the work
he's doing. Robert is planning on greatly extending XML for <SCRIPT>'s entity handling and I want
to make sure your two patches work together. 

* Update the pre-made event handler file

* Add a testcase or two (however many you think appropriate) to the SAX and W3C DOM test suites.

* If you would like, update the SAX and DOM documentation for entity handling. If you would rather
not, I'm just fine with a brief blurb from you in an Email describing exactly how the SAX and DOM
parsers should act and how a programmer would go about using your change. I'd be happy to update
the docs accordingly.


Thanks for your offer! 


Best regards,

David
