Hi Cecilio,
sorry again for the delay...

great - nice addition to the sample; could you submit it as a patch?
It's much easier to apply in that form (just do a "cvs diff -bu2
>sample.patch" in wxXml2\sample).

aren't these two issues the same ?
I'd simply write:
wxFileName oFN(pNode->GetSystemID());
if (oFN.IsRelative())
oFN.MakeAbsolute(wxPathOnly(m_sMainFilename));

I'll look at it....
Thanks,
