Hello, I'm using the following regular expression (borrowed from the Perl Cookbook) to extract links from html:
@links = m/<A[^>]+?HREF\s*=\s*["']?([^'" >]+?)[ '"]?>/sig;

I am wondering if anyone has a suggestion as to how I would extract a list of links from a block of text without any html tags, i.e
"this is a link, http://bob.com/page"
and
"so is this, but with a query string and a trailing period, http://bob.com/page?elem=val&elem2=val2.".

I'm reading through the perlre documentation, but I'm not very good yet, so any suggestions would be helpful.
Thanks!
