Ok, I can get it to work by putting a space after the final ]
m/href\s*=\s*['|"](.*)['|"] /i
instead of
m/href\s*=\s*['|"](.*)['|"]/i
But when I try
m/href\s*=\s*['|"](.*)['|"]\s*/i
or
m/href\s*=\s*['|"](.*)['|"] */i
It doesn't work. Does anyone know why?

Subject: [ cf-dev ] OT - Perl RegEx
I'm trying to extract the href from a <a> tag. So from the one below I want
http://www.google.com
my $description = 'Some text <a href = "http://www.google.com";
target="_blank">www.google.com</a>';
my $href = "";
if ( $description =~ m/href\s*=\s*['|"](.*)['|"]/i ) {
$href = $1;
} else {
$href = "No find";
}
print "href: $href\n";
This works if the <a> tag only has the href attribute, but when another is
added, like the target above, it pulls out:
http://www.google.com"; target="_blank
which isn't what I want.
m/href\s*=\s*['|"](.*)['|"]/i
My understanding of the above line is,
m/href match starting from "href",
\s* then zero or more white space,
= then "=",
\s* then zero or more white space,
['|"] then either a single or double quote,
(.*) then anything(this being the bit I want to pull
out),
['|"] then either a single or double quote
/i non case sensitive
How do I tell it to stop at the first single or double quote after the
first?
Also, I'll be going on to try and allow no quotes around the href attribute,
a client will be supplying the input for this. Can anyone think of other
ways of improving this?
Thanks
