Hi, Using encode_entities makes this sort of thing happen: XML Parsing Error: undefined entity Location: http://XXX.YYY.ZZZ/ and points to the relevant entity. I think using encode_entities_numeric would help a lot with this. This is just a naïve assessment, but this would prevent xml-like pages being non-xml.
