Question

This should be a simple regex but I can’t seem to figure it out.

Can someone please provide a 1-liner to take any string of arbitrary HTML input and populate an array with all the Facebook URLs (matching http://www.facebook.com) that were in the HTML code?

I don’t want to use any CPAN modules and would much prefer a simple regex 1-liner.

Thanks in advance for your help!

Obligatory link explaining why you shouldn’t parse HTML using a regular expression.

That being said, try this for a quick and dirty solution:

my $html = '<a href="http://www.facebook.com/">A link!</a>';
my @links = $html =~ /<a[^>]*\shref=['"](https?:\/\/www\.facebook\.com[^"']*)["']/gis;
