You're right. I looked at the source and found this abomination:
s{<a\s+.*?href\=(.*?)>(.*?)</a>}{ ... }isgxe;
Ouch. There are so many ways that this can go wrong: "a" tags with a "name" and no href attribute, whitespace around the "=", ...

There are modules made espacially to extract links from HTML, for example HTML::LinkExtor and HTML::SimpleLinkExtor. Using one of those would have been a much safer approach.

But at least, this module takes "robots.txt" files in consideration, which is the polite thing to do, and probably one of the first things to go in a more naive approach. So that is good.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
