Here is a try on the same idea (<> and ><)
But I have prefered not to load the complete file in memory.
It's my really first try in c++, then I have surely not use really well
the objects.
off course, I suppose there is no syntax errors in xml, then I do not
make controls.

George Makrydakis a écrit :
No misunderstandings please... This is what I was working on:
The only bug to fix has to do with DTD (minor one but it crashes
it...)
Working together means that I must do marathon running?
Geez..., do not mix premature constructive criticism with the need
to not be
releasing buggy stuff..
The code below works if you take out DTD elements out of any xml
file that is VALID.
Handles the <,> and >,< pairs correctly no matter how weird the
syntax is...
IT IS BUGGY BUT IT IS UNINFORMED, and most of all *SMALL*
Thank you for making my trouble worth nothing, you could not wait
a couple of days more, could you...
