I suggest that you've failed to accept what many have been telling you: The presence of angle brackets around sequences of certain characters might create "tags", but that does not make it XML. "XML" is a well-defined language. Claiming that text such as; <elem attr="<"&<Bob"/> is XML doesn't make it so. There are explicit rules in the definition of the language XML that prohibit attribute values containing <, &, and the quoting character itself unless they are properly "escaped". Violation of those rules means that the text doesn't meet the definition of XML. Would you, for example, expect a C processor to process this text properly: switch (flag] { ... ) even though the right square bracket was pretty "obviously" supposed to be a right parenthesis and the right parenthesis a right curly brace? I haven't encountered a C processor that would make those corrections -- they all seem to report syntax errors and expect me to make the corrections. I don't find that unreasonable. I'm no longer a software developer (although I was for many, many years), and yet I've been able to write fairly simple code in a couple of different languages that pseudo-parses input text that claims to be XML, locates certain aberrations that my application typically produces (e.g., & and < in what were intended to be attribute values, -- in what were intended to be comments), and corrects those specific errors (e.g., replacement with character references and insertion of a space between the hyphens). Full parsing is rarely needed, depending on the precise errors that you intend to fix. I'm sure that you can do the same without significant overhead.
