Reading Soap response using C# WPF - soap

Question

I have the following response from a SOAP message. I need to read the values from the REQUEST_STATUS tag and the RESULT tag and put it in a datatable to update the table inside my database.
Please help me as I am doing this for the first time.
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<CalculationResponse xmlns="http://www.someurl.com/">
<OUTPUT>
<REQUEST_STATUS>
<IS_SUCCESS>true</IS_SUCCESS>
<IS_PARTIAL_SUCCESS>true</IS_PARTIAL_SUCCESS>
</REQUEST_STATUS>
<RESULT>
<Value>
<inset1>1<inset1>
</Value>
<Value>
<inset2>2<inset2>
</Value>
</RESULT>....
C# Code I tried:
XDocument doc = XDocument.Load(Environment.CurrentDirectory + "\\out.xml");
XNamespace ns = #"http://www.someurl.com/";
bool validation = false;
var root = doc.Descendants("CalculationResponse").Elements("OUTPUT").Elements("REQUEST_STATUS");
var valuestr = from r in root.Elements("IS_SUCCESS")
select r.Value;
validation = (valuestr.ToString()=="true")?true:false;
I always get the valuestr has no results in the collection.

Here is the code I made it to achieve:
C# Code:
XNamespace ns = #"http://www.someurl.com";
bool validation = false;
var parent = doc.Root.Descendants(ns + "CalculationResponse").Descendants(ns + "OUTPUT");
var valuestr = (from r in parent.Descendants(ns + "REQUEST_STATUS").Descendants(ns + "IS_SUCCESS")
select r.Value).ToList();
validation = (valuestr[0] == "true") ? true : false;
