Here's a hypothetical. Say there is an client I'm working with that needs to return Valid XML from their system. They've given me XML Schemas and said they are representative of the XML returned. Since Valid follows Well-Formed, sounds good.
Then someone mentions, "oh, well, we can't guarantee that there won't be some < or > or & in the element content. But, that's no problem, right?"
I said, "Well, then technically you are not sending us XML. If you can't escape (or CDATA) out the stray content with < >, then you're not even returning less-than/greater-than delimited files. What if I gave you content like this "123123324","2003-04-05","Scott ",Hans,"elman","Portland?" We have to agree on some fundamentals here. The XML 1.0 spec (and all tools based on it) is very specific." (They won't even CDATA the stuff)
The response? "Well, that's a purist's viewpoint."
I guess I got too mired in the Judeo-Christian Ethic of "Thou shalt not return malformed XML."
QUESTION: What level of Dante's Inferno would I be relegated to if I pre-process this XML-y (pronounced: 'smelly') to make it well-formed?
