Tricky PHP preg_replace

I’m trying to edit a RSS feed so the syntax is compatible with a RSS parsing script my site uses. Here is the RSS feed.
Here are the two strings which I need to edit:

<media:content width="1600" url="http://lh3.ggpht.com/_YcQ1Dmq5PFY/SL-wC7SQVII/AAAAAAAAC6Q/NpfNgIZZDTA/s1600/DSC00242.JPG" medium="image" type="image/jpeg" height="1200"/>

<media:thumbnail width="288" url="http://lh3.ggpht.com/_YcQ1Dmq5PFY/SL-wC7SQVII/AAAAAAAAC6Q/NpfNgIZZDTA/s288/DSC00242.JPG" height="216"/>

I need to change them so they appear as:

<content>http://lh3.ggpht.com/_YcQ1Dmq5PFY/SL-wC7SQVII/AAAAAAAAC6Q/NpfNgIZZDTA/s1600/DSC00242.JPG</content>

<thumbnail>http://lh3.ggpht.com/_YcQ1Dmq5PFY/SL-wC7SQVII/AAAAAAAAC6Q/NpfNgIZZDTA/s288/DSC00242.JPG</thumbnail>

I’ve been trying for a long time now and have come up with a hideous mess of PHP!
Any ideas? Thanks.

How about this?

php Code:

Original - php Code

<?php
 
$content = '<media:content width="1600" url="http://lh3.ggpht.com/_YcQ1Dmq5PFY/SL-wC7SQVII/AAAAAAAAC6Q/NpfNgIZZDTA/s1600/DSC00242.JPG" medium="image" type="image/jpeg" height="1200"/>';
$thumbnail = '<media:thumbnail width="288" url="http://lh3.ggpht.com/_YcQ1Dmq5PFY/SL-wC7SQVII/AAAAAAAAC6Q/NpfNgIZZDTA/s288/DSC00242.JPG" height="216"/>';
echo preg_replace('/^<media:(content|thumbnail)\s.*url="([^\s"]+).*/', '<$1>$2</$1>', $content) . "\n";
echo preg_replace('/^<media:(content|thumbnail)\s.*url="([^\s"]+).*/', '<$1>$2</$1>', $thumbnail);
 
?>

Thanks for the quick reply, i should have mentioned how i was fetching the feed. Here is my script:

php Code:

Original - php Code

<?php
$rss = file_get_contents('http://pipes.yahoo.com/pipes/pipe.run?XML=http%3A%2F%2Fpicasaweb.google.com%2Fdata%2Ffeed%2Fapi%2Fuser%2Fjimeagle%2Falbumid%2F'.$  _GET['a'].'%3Fthumbsize%3D288%26imgmax%3D1600&_id=_ps93kMh3hGd_2Ub3nBDOQ&_render=rss&itemname=entry');
$rss = preg_replace('/^<media:(content|thumbnail)\s.*url="([^\s"]+).*/', '<$1>$2</$1>', $rss) . "\n";
$rss = preg_replace('/^<media:(content|thumbnail)\s.*url="([^\s"]+).*/', '<$1>$2</$1>', $rss);
echo $rss;
?>

I tried to adapt the code you gave me but it didnt work. I am hosting it here.

$fp = file('http://jimeagle.com/site/pictures_rss.php?a=5241893999118690321'); foreach ($fp as $line) { echo preg_replace('/(\s+)<media:(content\|thumbnail)\s.url="([^\s"]+)./', '$1<$2>$3</$2>', $line); }

$fp = file('http://jimeagle.com/site/pictures_rss.php?a=5241893999118690321');
foreach ($fp as $line)
{
    echo preg_replace('/(\s+)<media:(content|thumbnail)\s.*url="([^\s"]+).*/', '$1<$2>$3</$2>', $line);
