Display CDATA with XSL

I've been playing around with it and there's something I can't figure out.

The XML is based of an RSS Feed. Here's a example of XML I am trying to play with.

<item>
   <title>Dinner at Chilis</title>
   <link></link>
   <description>
       [!CDATA[<div><b>Location:</b> Chilis </div>
                     <div><b>Start Time:</b> 4/21/2010</div>
                     <div><b>Description:</b> Dinner at Chilis </div>]]>
    </description>
</item>

Here's a part of the XSL I've been playing around.
<xsl:template match="item">
    <xsl:value-of select="title"/>
    <xsl:value-of disable-output-escaping="yes" select="substring-before(substring-after(description, ']]'), '[CDATA[') "/>
</xsl:template>

I'm not sure why it's not displaying the string.

My previous code was like this:
<xsl:template match="item">
    <xsl:value-of select="title"/>
    <xsl:value-of disable-output-escaping="yes" select="description"/>
</xsl:template>
It displays, but I won't have control on how to select the specific text in the description tag.

It's something I want to learn how to do it. I'm still a beginner in XSL so my apologies for being a newbie. Tongue out

EDIT*
Ok. I got it.
It displays only the first line though. lol. Here's the code I have right now.
<xsl:template match="item">
    <xsl:value-of select="title"/>
    <xsl:value-of disable-output-escaping="yes" select="substring-before(substring-after(description, '&lt;div&gt;'), '&lt;/div&gt;') "/>
</xsl:template>

So far so good. I'll play around a bit more.

The above will give you this:

Code:

<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">

Perlmod is a program that will help you manage Perl Modules.

http://sourceforge.net/projects/perlmod/files/latest/download

A Perl module is a discrete component of software for the Perl
programming language. Technically, it is a particular set of
conventions for using Perl's package mechanism that has become
universally adopted.[discuss] A module defines its source code to be
in a package (much like a Java package), the Perl mechanism for
defining namespaces, e.g. CGI or Net::FTP or XML::Parser; the file
structure mirrors the namespace structure (e.g. the source code for
Net::FTP is in Net/FTP.pm). Furthermore, a module is the Perl
equivalent of the class when object-oriented programming is employed

Now we'll see an easy way to manage them, install, list, delete
(uninstall) from the command line.
