Description

Have you wanted to added a Facebook Like Button to your site? Here's a basic utility allowing you to do that easily.

Basic usage:

Import this utility to your existing xslt template and then call the template like so...

<xsl:call-template name="facebook-like">
   <xsl:with-param name="url-to-like" select="'http://site.com'"/>
 </xsl:call-template>

The "url-to-like" parameter is required, other than that you can customize your output with the other optional parameters. The Facebook Like Reference will explain those optional parameters are.

IMPORTANT NOTE: (from mqchen) Just a tip; I think you need to add two namespaces in the html tag for it to work in some IE versions. xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml"
