It appears to only be licensed under the W3C "IPR" license. The IPR is
much better than LPGL (for Apache's sake).

hehe. cool.

It would be preferable to have a SAX interface from the parser, because
mod_dav uses its own tree structure. Without that, some serious munging
would need to occur to get mod_dav to work with gnome-xml.

On the other hand, other modules may prefer to receive a DOM-like
structure from the parser (it can certainly simplify a lot of things).
Those modules could use gnome-dom on top of gnome-xml?

btw, I saw a reference to gnome-xml in the current Linux Journal issue,
in the article about GNOME. Kind of funny because it was just last night
that I read it, and I had intended to look up gnome-xml for just this
reason (as a potential expat alternative).

Cheers,

p.s. I stripped Expat down to 19 files and no subdirectories, which
builds libexpat.a. Now to incorporate the thing into the Apache build
process...

  Actually it's released under both licences.

  There is some kind of SAX interface, but it's not very well tested nor
debugged. Moreover it's probably not complete. Send me the interfaces
you're using I will see what I can do.

  Gnome-dom is just a DOM compliant set of interfaces on top of gnome-xml.
The tree produced by the parser is really close to a DOM view.

   Oh, yes Miguel wrote an article. Funny :-)

  I suggest you subscribe to xml@rufus.w3.org (majordomo) so we can move
this out of Apache list, most listeners probably don't care much about
those issues.
