ActionScript 3 - Retrieving xml data and matching extension to execute a particular function?

I have an XML file that has location pathways of files to load. eg.
<sample>
<file>audio/sample.mp3</file> or
</sample>
<sample>
<file>slideshow1.swf</file>
</sample>

In my movie, if you click a button, it will load file [0] or [1] using the XML file to provide the pathway. I am trying to create a script that will look at the extension .mp3 or .swf and depending on the extension, will execute a certain function.

How do I make my movie only look at the last 3 letters of the file text in the XML file??

Thanks

You can use substr on the "file" XML node and check what it returns, in this case the last 4 characters:

Code:

var test_filenames:Vector.<String> = new <String>["dog.exe", "cat.exe", "elephant.php", "bird.gif"];

// .exe
trace(test_filenames[0].substr(-4));

// .php
trace(test_filenames[2].substr(-4));

// Execultable
switch (test_filenames[1].substr(-4))
   {
      case ".exe" :
         trace("Execultable");
         break;
      case ".php" :
         trace("PHP file");
         break;
      case ".gif" :
         trace("Image file");
         break;
   }
