Hello how's everyone doin'? I need help with the regular expression in PHP (using preg_match_all) that would extract the url and the image of these two:

<A HREF="movie1.mpg"><img name="movie1" src="images/tn_01.jpg" width="320" height="240" border="0" alt="Play Movie" title="Play Movie" class="vid_th"></A>

<a href="movie2.mpg"><img src="images/tn_01.jpg" width=320 height=240 border=0 class="fhg_vid"><br><img src="images/play.gif" width=320 height=48 border=0></a>

If you notice on the second one, there are two image sources: "images/tn_01.jpg" and "images/play.gif". I would only need to extract the first image source ("images/tn_01.jpg").
Also, I would only need to extract jpg image formats.

Currently, my expression is:
$expr = '@<a[^>]*href="([^"]*)"[^>]*>[^>]*<img[^>]*src="([^"]*)"[^>]*>[^>]*</a>@Usi';

This works fine with the first given but it doesnt extract the jpgs with the second one. I'm new with regexp so i'm still a little confused. I would appreciate it very much if you could provide an explanation with your expression.

Thanks much! have a nice day y'all!!!

Your regex is almost right.

Change your last [^>]* to .*?

Your regex assumes that there will be no > characters following the end of the first image tag.  Your second link contains two > characters prior to the closing </a> tag, so the match fails.
