HttpWebRequest.GetResponse() returning Envelope and [CData and Encoded values

I'm am using the HttpWebRequest.GetResponse()  to get an XML file from a client.

The client XML is returned with everything decoded.
The client is returning the Envelope.
The client is returning part of the data inside a [CDATA wrapper. It returns several required elements, then it returns a [CDATA with the remaining elements.

I want to deserialize the data eventually.

If I try to write to an XMLDocument it errors:
XmlDocument xmlResults = new XmlDocument();
                            xmlResults.XmlResolver = null;
                            xmlResults.LoadXml(soapResponseMsg);


I have tried stripping out the Envelope.
Decoding the &lt; and &gt; back to < and >.

But when I deserialize the raw data, it doesn't find the values between the [CDATA so it doesn't deserialize anything within that.

Then I tried stripping out the CDATA, but then it errors, because the client has data within the elements with < and > symbols, so then I get an error:

>Data at the root level is invalid. Line 1, position 1."

<class>GVWR<26001</class>

So it thinks the < symbol above is a command!

I have tried all kinds of encoding tricks.
request.ContentType = "text/xml;charset=\"utf-8\""; // add escaped
request.Accept = "text/xml";

and

Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
using (StreamReader reader = new StreamReader(response.GetResponseStream(), encode))

... hoping there is some setting that will retrieve the XML data with the < > as they should be, but leave the body &lt; as it should.

Is there something?

Thanks!

I don't understand what you have tried?  If you have 3.5 or higher, then you should be able to use LINQ-to-XML, which is the XDocument class.  You should be able to use the original XML, and parse out what you need.

I have to save this as a string and store it in the database as a blob. Then a later web service will retrieve the blob and deserialize the data.

But first before it saves to the database, it tries to write to an xmldocument, to make sure it is valid XML, and it fails because of the &lt;, the envelope and the CData wrapper embedded within the body of the XML.

XmlDocument xmlResults = new XmlDocument();
                            xmlResults.XmlResolver = null;
                            xmlResults.LoadXml(soapResponseMsg);

Can you show me an example of the XML, and the validation errors, please?

I found the solution.

I use the SoapEnvelope class to retrieve the envelope, then load the envelope body into an XmlDocument. Then I strip out the <![CDATA[ and its closer.

Thanks!
