currently no; that's because wxXml2 API derives from wxXml API because 
when I wrote it I wanted to port some wxXml code to a newer API with DTD 
validation and thus I made wxXml2 API mostly compatible with wxXml one, 
which has no GetChildCount() methods.

However I agree this would be useful to have. Patches welcome :D

we could add a new GetChildrenCount(const wxXmlNode &tofind, bool bNS = 
TRUE, bool recurse = TRUE) function to return it

I would add a GetChildrenCount() const function for this.

it highly depends on how to you want to organize your parser.
For me, the pattern I copied & pasted in previous mail has always been a 
winning pattern ;)

I.e. you scan all the XML document, handle unknown tags in the else{} 
part, and call subroutines to load other nodes in other elseif{} branches.

It's a lot of time I don't look at XML Schemas, SAX parser, etc.
You can get an idea of the "low-level" libxml2 API looking at
