Getting CDATA content which is a slideshow

I have an XML represented by this http://ift.tt/1pBxMoN. I was able to access the title and link via my xsl which looks like this

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://ift.tt/tCZ8VR" version="1.0"
    xmlns:media="http://ift.tt/W3lYmr">
    <xsl:output method="xml" indent="yes"/>
    <xsl:template match="/">
        <rss xmlns:georss="http://ift.tt/N7lROd" xmlns:twitter="http://api.twitter.com" xmlns:atom="http://ift.tt/r5ut6F" version="2.0">
            <channel>
                <author>
                    <xsl:text>Content-Feed-Pics</xsl:text>
                </author>
                <xsl:for-each select="rss/channel/item[position() &lt; 30]">
                    <item>
                        <title><xsl:value-of select="title"/></title>
                        <!--author><xsl:value-of select="dc:rss/dc:channel/dc:item/dc:creator"/></author-->
                       <!--icon>
                       <xsl:value-of select="concat(entities/media//media_url,':thumb')"/>                    
                       </icon-->


                        <link><xsl:value-of select="link"/></link>
                        <description><xsl:value-of select="description"/></description>
                        <pubDate><xsl:value-of select="pubDate"/></pubDate>
                    </item>
                </xsl:for-each>
            </channel>
        </rss>
    </xsl:template>


</xsl:stylesheet>
​

The two issues are to get the CDATA content for node which is a slideshow enclosed within % %. The second issue is there are certain nodes like and with namespaces. I tried adding dc: namespace to all the nodes in their path but the nodes were not getting accessed.

Kindly advise
