Subject: Reorder a XML file by distance from a location

Hi

I'm quite the newbie and I'm looking for some help. I need to do
something quick and it doesnt look so hard.

I have this RSS file on my computer (below) and I need to produce a very
similar RSS file but with the items ordered according to the distance
from a given location using the latitude and longitude. I'm trying to
use rexml, but I can't really get anything good. I don't figure how
sorting works.

Can someone give me some hints or advice?

======
<?xml version="1.0"?>
<rss version="2.0">
   <channel>
      <title>something</title>
      <description>myfeed</description>

      <item>
         <title>somewhere</title>
         <link>http://link</link>
         <description>niceplace</description>
        <geo:lat>45.6743546527171</geo:lat>
         <geo:long>130.7628651374888</geo:long>
      </item>

etc.

   </channel>
</rss>
