Something like:
use strict;
use warnings;
my $webStr = <<EOS;
data-src-hq="image location1"
<p>other stuff</p>
<p>data-src-hq="image location2"</p>
EOS
my @matches = $webStr =~ /data-src-hq="([^"]+)"/g;
print join "\n", @matches, '';
Prints:
image location1
image location2
Note the /g switch on the regex.
