I bet I was one of the few who knew that you were talking about the
DOMDocument object instead of widgets.
GetLastChild() should work. Maybe if you post some sample XML that
you are using and the code that uses GetLastChild that does not work,
someone can figure out what is going on.
I note that you use doc->GetLastChild to get the count and then doc-
> GetFirstChild to get the parent of the element list. But I think
that both end up referring to the same object, so that should be ok.
You might try turning on the option to ignore ignorable whitespace.
Sometimes ignorable whitespace objects appear in the tree in
unexpected places and can interfere with accessing the elements.
