Wildcards in XSL

System

This may seem simple and I hope it is. I am trying to use a wildcard in XSL to basically perform an action when the value that is returned is a .pdf file. I have attached the code I am using at the moment. I simply want it to automatically place an PDF image next to the link if a .pdf file is chosen. I currently am using a flag to place the icon but I want it to do it automatically.

Thanks in advance

Something like this: <xsl:when test="contains($thelink, '.pdf')"> ??
