Answer 1

Although the only fully correct way to do this is not to use regular expressions, you can get what you want if you accept it won't handle all special cases:

preg_match("/]*?>.*?/i", $str, $match);
// Use this only if you aren't worried about nested tags.
// It will handle tags with attributes

And

preg_replace(""/]*?>.*?/i", "", $str);
