Thanks for your answer, but I think that either I wasn't clear, or I'm
missing something. I have no problem with the way the mixed content of
an element is stored. My problem is with my understanding of
xmlNodeSetContent: before adding new content to an element node, it
removes ALL child nodes - both text nodes (understandable) and element
nodes (no so understandable, at least to me). I'm looking for a function
that replaces the child text nodes (and I'm not too concerned with where
the new text nodes go - at the end would be fine), while leaving the
child element nodes intact.
I'll write such a function if I have to - I just want to be sure that I'm
not reinventing the wheel.
Thanks,
Harry
