PHP RegEx woes

[AfterEffect]

Hey all!

Still fairly new to RegEx, and really struggling to find an expression to get the URL out of this text:

<script type="text/javascript">
					document.write('<li><a href="/oyster/journeyHistoryThrottle.do?_qs=_qv%3Dc2115ef6e2db4509db5d5f1b044f09009b4d3e30">Journey history</a></li>');
				</script>
				<noscript>
					<li><a href="/oyster/journeyHistory.do?_qs=_qv%3Dc2115ef6e2db4509db5d5f1b044f09009b4d3e30">Journey history</a></li>
				</noscript>

The problem is that the value after _qs=_gv changes with each session.
Do you have any ideas how I could get this working? :S

The value I would need is in bold:

Spoiler

document.write('<li><a href="/oyster/journeyHistoryThrottle.do?_qs=_qv%3Dc2115ef6e2db4509db5d5f1b044f09009b4d3e30">Journey history</a></li>');

Never mind, found it! Sorry but a mod can close/delete this now

Solution:
$pattern = "/<a href=\"\/oyster\/journeyHistoryThrottle.do(.*?)\">Journey history/s";

edit: Thanks aharvey for the help

lol, it's always the way well done

Defo need to learn this myself!

Seems very powerful

Just made a script that logs into my TfL journey history page, parses the data, and then injects it into a database... and now it all works \0/
