The regular expression that Markdown passes to Text::Balanced to match opening tags contains a backreference to the attribute value quote character. Text::Balanced wraps this expression in another set of parentheses when matching for a nested tag, which breaks this backreference. I don't know whether this is a bug in Markdown or Text::Balanced, nor do I see a good way to fix it. Help! -- Matt -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
