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
