xml and cdata

[KKKKKRTtTT]

I have an xml document that looks like this:

<OUTPUT version="2.0">
    <RESPONSE>
        <LOAN_DATA 
            loan_id="xxxx" 
            loan_number="1111" 
            loan_type="HE" 
            status_code="OK">
        <![CDATA[<MORTGAGE_LOAN xmlns="http://www.something.com/CLF" version="1.0">
            <APPLICANTS>
                <APPLICANT 
                    is_declined="N" 
                    first_name="MARISOL" 
                    last_name="TESTCASE" 
                    m_initial="L" 
                    middle_name="L" 
                    ssn="000000001" >
                              </APPLICANT>
            </APPLICANTS>
                   </MORTGAGE_LOAN>]]>
        </LOAN_DATA>
    </RESPONSE>
</OUTPUT>
I can successfully read down to the CData section and can even access the CData section using the following:

string cData = "";
            XmlDocument xDoc = new XmlDocument();
            xDoc.LoadXml(loanData);

            XmlNode node = xDoc.DocumentElement.SelectSingleNode(@"RESPONSE/LOAN_DATA");
            XmlNode childNode = node.ChildNodes[0];
            if (childNode is XmlCDataSection)
            {
                XmlCDataSection cdataSection = childNode as XmlCDataSection;
                cData = cdataSection.Value;
            }

cData now holds:

<MORTGAGE_LOAN xmlns="http://www.something.com/CLF" version="1.0">
            <APPLICANTS>
                <APPLICANT 
                    is_declined="N" 
                    first_name="MARISOL" 
                    last_name="TESTCASE" 
                    m_initial="L" 
                    middle_name="L" 
                    ssn="000000001" >
                              </APPLICANT>
            </APPLICANTS>
                   </MORTGAGE_LOAN>

What I want to do is to treat this as a new xml document and read it accordingly. When using the following node is always null. I've tried several versions of the xpath and it always returns null.

XmlDocument cDataDoc = new XmlDocument();
cDataDoc.LoadXml(c//node is always null here
 XmlNode node =cDataDoc.DocumentElement.SelectSingleNode("MORTGAGE_LOAN/APPLICANTS/APPLICANT");

Any help would be great. Thanks ....

If you want to read this xml document then used these links as a reference (there's nothing with your ASP.net code):
