Filename to IPTC Title, but without extension. (Currently using DAM script)

Question

Hello,
Apologies if this isn't the correct forum to ask this question:
I am currently using the DAM Filename to Title script with Bridge CS4 - http://www.damuseful.com/pages/PimpMyBridge.html - to get the filename into the IPTC title script. This however puts in the extension into the title field also. So a JPG file named 2000 ends up with 2000.JPG in its Title field. I wish to not have the extension appear in the Title field.
Is this possible by modifying the DAM script / using any other freely available script.
In case it helps, this is what the DAM script currently looks like:
#target bridge
if ( BridgeTalk.appName = "bridge" )
//This script copies selected thumbnails' filenames to the title field
//Also shows how to add menu items
//The AdobeLibrary scripts must be loaded
//This script was created by John Beardsworth www.beardsworth.co.uk/ and modified by Peter Krogh www.DAMuseful.com
//This script may be freely distributed and modified
// Let's create our menu
    var menu = MenuElement.create( "command", "Write Filename to IPTC Title Field", "at the end of Tools");
    menu.onSelect = function(m)
var getFolderChildren = true ;
var filesOnly = true ;
var thumbs = getBridgeThumbnails ( TYPES.PHOTOSHOP_OPENABLE, getFolderChildren, filesOnly) ;
for ( var i = 0; i < thumbs.length; i++ )
{ thumb = thumbs[i];
   md = thumb.synchronousMetadata;
   md.namespace ="http://ns.adobe.com/photoshop/1.0/";
   md.Title = thumb.name;
   Window.alert ("Done " + i + " records");
There are also 3 other Adobe Library scripts that come with the download.
I know absolutely nothing about scripting, so baby-steps would be appreciated.
Many thanks.

Change:
md.Title = thumb.name;
To:
md.Title = decodeURI(thumb.name).replace(/\.[^\.]+$/, '');
