Well then it's not expected to be processed as XML, so why does this concerns libxml2 ? > The questions is what to do. No the question is "are those XML application you're using or communicating with ?", if they don't do normalization nor replace the entities references then the answer is no. You're not manipulating XML but something which looks like XML but isn't expected to be processed as such. I'm not fond of adding yet another set of APIs or switches to cope with yet another pseudo XML parsing framework. That's why we went to errors being fatal in XML and stringent on spec errors violations. Those tools don't allow you to benefits from the standardization benefits, complain about them not about libxml2 being compliant. > The option of filtering the output again seems awkward to me... they process XML in broken ways, that's why. > And if i understand the xml specs correctly sending and \r\n as _output_ > is considered valid (http://www.w3.org/TR/REC-xml/#NT-S) since they are > to be removed in input anyways.

No because *any* compliant XML parser must do the replacement on input and replace numeric character references by the character with the associated code point when passing data to the application. They have problem processing XML input generated by libxml2 only because they are not compliant. They are not XML compliant applications, period. Sorry you will have to cope with this, as this has no place in an XML toolkit IMHO, or use the HTML serializer or serialize the trees yourself or post process. The added work on your side is only due to non compliance on theirs.
