In almost any situation, there are those who prefer maxims to thinking---ignore them. With specific regard to the odd web scrape, there are a couple of things that can be a problem.
  • The need to handle nesting.
  • The need to survive arbitrary changes in the source.
The first can be handled by tight expression bounding or by using something like Text::DelimMatch or Text::Balanced. You manage the second by vigilance---patch it when needed.

As for those who knee jerk instead of thinking, since many of them have no experience witting parsers (formal or ad hoc) they fail to see that the regex approach is a form of parsing, just without the overhead of dealing with things that don't matter.

    [Lady_Aleena]: This evening, I thought to myself, "I would love to search Netflix for 100 randomfilms from my database to see if they have them." So I went to CPAN to see if there were a modiule which could do such a thing. There is, but GUH! ...
    [Lady_Aleena]: ... Does it have to be that hard and complex to use to do a search on Netflix?
    Lady_Aleena grumbles.
    [Lady_Aleena]: I really need to get back into the swing of Perl. I'm forgetting things from lack of use. I don't know how behind I am too.
