Hey all!

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

PHP: 
<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:

document.write('<li><a href="/oyster/journeyHistoryThrottle.do?_qs=_qv%3Dc2115ef6e2db4509db5d5f1b044f09009b4d3e30">Journey history</a></li>');
 
I can do this in Python (if I remember how) but can't help specifically help with the js code you need here but maybe look at it with a few suggestions.

Although the value after _qs=_qv changes, can you not assign it to a variable, find the position of =" and "> as what you want always ends with this and then assign everything in between to a new variable to use?

I should be going to bed but now you've got me pondering...*goes of to look at code*
 
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
