Hi,

I've been reading through the sources for gnome-xml the last few days,
and I've got a couple of questions:

When using SAX shouldn't you be able to specify the userData that is
always passed as first argument to the handlers? As it is,
ctxt->userData is just cleared when the SAX interface is used, whereas
the default SAX handler uses this to get at the xmlParserCtxt. If you
were to do anything serious [ie. other than 'printf("startTag: %s\n",
...)'] _a_n_d threadsafe you would need this. It's a fairly
simple extension, something like

    xmlSAXParseMemory(xmlSAXHandlerPtr sax, void *userData,
                      char *buffer, int size, int recovery) {
        [...]
        if (sax != NULL) {
            ctxt->sax = sax;
            ctxt->userData = userData;
        }

and similar for the rest of xmlSAXParse*.
  
Another thing: since this is an XML parser for Gnome, how come it is
kept independent of glib? (I can see from the ChangeLog that snprintf
was preferred over g_snprintf). Surely glib would save some lines of
code and if GHash was used instead of xmlElementTable and others maybe
a speedup could be expected?

regards, Kristian
