Answer 1

You're not trying to remove special characters from an XML Document.

You're trying to convert a non-XML document to XML.

To do that you need to parse the non-XML document, and to do that you need to know (a) the grammar to which it conforms and (b) the rules for how this grammar maps to the grammar of XML.

You haven't told us anything about this grammar; you've just given one example of a non-XML document, and that's not enough to infer the general rules.
