You can't build a regular expression for any grammar. You can for some grammars but those are only a simple subset. For example, checking parens balance is impossible with common (not recursive) regular expressions only, and even with recursion it soon reaches its limitations.
TextMate grammars support recursion, it's possible to define a grammar with balanced parentheses [1].
