in thread regex on XML

Perhaps, but it has nothing to do with it being valid XML or not: it is just about having balanced quotes.

    Yes it is - if you don't encode apostrophes inside an apostrophe quoted string your XML is immediately invalid. Same thing for double-quotes.

      Well I guess it is just a matter of semantics: XML does not need single and double quotes encoded, but it needs them balanced. Either way the XML is "bad".

      Most of the time you can get away with the encoding by putting single quotes within double quotes and vice versa.

        Er, these all fall into the category of syntax errors. XML is just more permissive about the places where you can get away without handling these particular characters specially. Really, when you next tell someone this you'll be incorrect if you artificially call this "balancing" but the other stuff "invalid". Its equally invalid either way. This isn't a sort of "well ... it was mostly ok" operation. XML validity is either 100% one way or the other. This just happens to be a rule that can tip your XML into being invalid.
