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?
