SPUG: Regex question

Let's say I'm parsing HTML using regular expressions and I want to find:

        <tag> ... </tag>

where the text within the tag body does _not_ contain the word 'Alpo'.

I've seen the following as a solution:

        $text =~ m|<tag>(?:(?!Alpo).)*</tag>|;

This seems really compute-intensive.  Is there a better way?
