  This tend to surprize people but since blank node elimination without
having read the DTD is a pure heuristic, the parser try to be as safe as
possible (though it's not possible to go back on nodes already parsed).
In general XML_PARSE_NOBLANKS is a deviation from the normal parsing
behaviour so in general I suggest to avoid it and just ignore the nodes
you know are purely formatting, the parser can't guess it 100%
