How to databind image file names without extention?

Hi Guys,

When databind image file names (Text="{Binding XPath=Image}" )
The entire XPath shows up, for example, "Images/Cat.jpg"
How to just get "Cat" only?

Here is the XML file:

<?xml version="1.0" encoding="UTF-8"?><dataroot xmlns:od="urn:schemas-microsoft-com:officedata" generated="2011-06-04T14:21:45"><Animal><ID>01</ID><Image>Images/Cat.jpg</Image></Animal><Animal><ID>02</ID><Image>Images/Cattle.jpg</Image></Animal><Animal><ID>03</ID><Image>Images/Cock.png</Image></Animal><Animal><ID>04</ID><Image>Images/Dog.jpg</Image></Animal><Animal><ID>05</ID><Image>Images/Goat.jpg</Image></Animal><Animal><ID>06</ID><Image>Images/Horse.jpg</Image></Animal><Animal><ID>07</ID><Image>Images/Mice.jpg</Image></Animal><Animal><ID>08</ID><Image>Images/Ox.jpg</Image></Animal><Animal><ID>09</ID><Image>Images/Pig.jpg</Image></Animal><Animal><ID>19</ID><Image>Images/Rabbit.png</Image></Animal><Animal><ID>11</ID><Image>Images/Tiger.jpg</Image></Animal></dataroot>
