parse

I've got some HTML files that need to be parsed and cleaned, and they occasionally have content with special characters like <, >, ", etc. which have not been properly escaped.

I have tried running the files through jTidy, but the best I can get it to do is just omit the content it sees as malformed html. Is there a different library that will just escape the malformed fragments instead of omitting them? If not, any recommendations on what library would be easiest to modify?

Clarification:

Sample input: <p> blah blah <M+1> blah </p>

Desired output: <p> blah blah <M+1> blah </p>
