Parsing HTML with regular expressions can only end in tears. I would suggest checking out HTML::Parser.

I think the closest thing to what you're looking for is the zero-width negative lookahead assertion. For example, /foo(?!bar)/ matches "foo" followed by anything that isn't "bar". See perlre for more information; negative lookaheads are difficult to master and can become quite complex.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
