This WSDL contains a policy section and an operation section
So on the basis of the operation anme and the URI attribute of Tag wsp:PolicyReference
I want to fetch the whole Policy XMl part from this WSDl

<wsp:Policy wsu:Id="p1">
     <sp:SignedParts>
     <sp:Body />
     </sp:SignedParts>
    </wsp:Policy>

There can be many policy but whose ID matched with URI value of Policy refence whose operation name i pass , that policy I want .

can u help me to fetch policy XML part.

When some one pass value of pOperationName variable as concat then output string should be following:

<wsp:Policy wsu:Id="p1">
 <sp:SignedParts>
 <sp:Body />
 </sp:SignedParts>
</wsp:Policy>

Done it using following Code

 private string GetPolicy()
        {
            XDocument wsdlDocument = XDocument.Load(_wsdlPath);

            XName operationElementName = XName.Get("operation", "http://schemas.xmlsoap.org/wsdl/");
            XName policyReferenceElementName = XName.Get("PolicyReference", "http://schemas.xmlsoap.org/ws/2004/09/policy");
            XName policyElementName = XName.Get("Policy", "http://schemas.xmlsoap.org/ws/2004/09/policy");
            XName idAttributeName = XName.Get("Id", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wsswssecurity-utility-1.0.xsd");

            var operationPolicy = from operation in wsdlDocument.Descendants(operationElementName)
                                  where operation.Attribute("name").Value == _operationSelected
                                  from policyReference in operation.Descendants(policyReferenceElementName)
                                  where policyReference.Attribute("URI").Value.StartsWith("#")
                                  let uri = policyReference.Attribute("URI").Value.Substring(1)
                                  from policy in wsdlDocument.Descendants(policyElementName)
                                  where policy.Attribute(idAttributeName).Value == uri            
                                  select policy.ToString();

            #region Removing Embedded Namespaces
            string temp = operationPolicy.FirstOrDefault();
            if (temp.Contains(Constants.WSPolicyNsURI.XMLNS_SP) || temp.Contains(Constants.WSPolicyNsURI.XMLNS_WSP) || temp.Contains(Constants.WSPolicyNsURI.XMLNS_WSU))
            {
                temp = temp.Replace(Constants.WSPolicyNsURI.XMLNS_SP, String.Empty);
                temp = temp.Replace(Constants.WSPolicyNsURI.XMLNS_WSP, String.Empty);
                temp = temp.Replace(Constants.WSPolicyNsURI.XMLNS_WSU, String.Empty);
            }

            #endregion
            return temp;
        }

    private string GetPolicy(string pWsdlPath, string pOperationName)
    {
        XDocument wsdlDocument = XDocument.Load(pWsdlPath);

        XName operationElementName = XName.Get("operation", "http://schemas.xmlsoap.org/wsdl/");
        XName policyReferenceElementName = XName.Get("PolicyReference", "http://schemas.xmlsoap.org/ws/2004/09/policy");
        XName policyElementName = XName.Get("Policy", "http://schemas.xmlsoap.org/ws/2004/09/policy");
        XName idAttributeName = XName.Get("Id", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wsswssecurity-utility-1.0.xsd");

        var operationPolicy = from operation in wsdlDocument.Descendants(operationElementName)
                              where operation.Attribute("name").Value == "concat"
                              from policyReference in operation.Descendants(policyReferenceElementName)
                              where policyReference.Attribute("URI").Value.StartsWith("#")
                              let uri = policyReference.Attribute("URI").Value.Substring(1)
                              from policy in wsdlDocument.Descendants(policyElementName)
                              where policy.Attribute(idAttributeName).Value == uri
                              select policy.ToString();

        return operationPolicy.FirstOrDefault();
    }
