they *are* part of the document, even if supposedly there only for
formatting, there is no way libxml2 can guess when finding a text
node with blank content whether it's there for formatting/niceness
or if this is user content.
The application programmer i.e. *you* are the only one knowing if
the text node is part of the application data or not. It's your job
to do the filtering, libxml2 can't do that for you.
