Extracting CDATA section using XSLT

In a XML message, we pass some data which we might not want to be parsed by xml parsers.
Characters like "<>" are illegal in XML elements.  To save such characters we use CDATA section in our xml message.
For instance in the following xml message, we use CDATA block to pass <metadata> to other end without parsing "<,>" signs.
eg:

    <ser:getArtifactContentResponse    xmlns:ser="http://services.generic.governance.carbon.wso2.org">
    <ser:return>
         <![CDATA[
   <metadata xmlns="http://www.wso2.org/governance/metadata">
    <overview>       
        <name>scannapp&lt;/name>
        <developerId>developer702&lt;/developerId>
        <stateId>2&lt;/stateId>
        <serverURL>http://abc.com&lt;/serverURL>
        <id>cspapp1103&lt;/id>
        <description>scann doc&lt;/description>
        <hostingTypeId>1&lt;/hostingTypeId>       
    </overview>
</metadata>
  ]]>
  </ser:return>
</ser:getArtifactContentResponse>

 

To extract the CDATA section,( here it contains xml message) we could use simple xslt script.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0" xmlns:ns="http://services.generic.governance.carbon.wso2.org">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" />
    <xsl:template match="/">
        <xsl:value-of select="//ns:getArtifactContentResponse/ns:return/text()" disable-output-escaping="yes"/>
    </xsl:template>
</xsl:stylesheet>

The output would be ;

   <metadata xmlns="http://www.wso2.org/governance/metadata">
    <overview>       
        <name>scannapp</name>
        <developerId>developer702</developerId>
        <stateId>2</stateId>
        <serverURL>http://abc.com</serverURL>
        <id>cspapp1103</id>
        <description>scann doc</description>
        <hostingTypeId>1</hostingTypeId>       
    </overview>
</metadata>
