I am using standard SAML2.0 Authentication engine for authentication purpose. I am able to access the JAVA objects using script attribute from SAML. But I need to send the XML objects as additional attributes in SAML response ( in assertion ). For this I am trying to hard code as below. If this works I can extend this to JAVA objects.

<resolver:AttributeDefinition id="TestAttr"
    xsi:type="Script" xmlns="urn:mace:shibboleth:2.0:resolver:ad">                                            
    <resolver:AttributeEncoder xsi:type="SAML2XMLObject"
   xmlns="urn:mace:shibboleth:2.0:attribute:encoder" name="TestAttr"
   nameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" />
   <Script><![CDATA[
     importPackage(Packages.edu.internet2.middleware.shibboleth.common.attribute.provider);
     importPackage(Packages.edu.internet2.middleware.shibboleth.common.attribute);
    importPackage(Package edu.internet2.middleware.shibboleth.common.xmlobject);
     TestAttr = new BasicAttribute("TestAttr");
     var text="<node>";
    text=text+"<content>test</content>";
    text=text+"</node>";
    var parser=new DOMParser();
       TestAttr.getValues().add(parser.parseFromString(text,'text/xml'));          
  ]]></Script> 
  </resolver:AttributeDefinition>

Any pointers to fix this issue. Thanks in advance
