That's not XML, then. A raw control character U+0002 anywhere means it's not well-formed and hence not an XML document.

In XML 1.1 only, one may include control characters encoded as character reference. So you might have tried to fix it up by doing a string replace for \x02 with  before parsing. However, you can't put character references in CDATA sections, so that's not going to fly either.

edit: you could probably fix it in the short-term, if you are absolutely sure that every stray U+0002 character is inside a CDATA section, by replacing each with:

However this is super-shonky. Whatever generated the faulty XML in the first place needs to be fixed. Go kick the person responsible for creating it!
