Get XElement from XDocument
Question
I have XML
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
...
I load xml into XDocument
XDocument xDoc = XDocument.Parse(xmlString);
and next i try to find XElement contains Body
I tried
XElement bodyElement = xDoc.Descendants(XName.Get("Body", "s")).FirstOrDefault();
or
XElement bodyElement = xDoc.Descendants("Body").FirstOrDefault();
or
XElement bodyElement = xDoc.Elements("Body").FirstOrDefault();
but bodyElement always is null .
If I try add namespace
XElement bodyElement = xDoc.Descendants("s:Body").FirstOrDefault();
I got an error about : .
If I remove s from XML
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<Body s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
...
Everything works.

You're trying to look in a namespace with a URI of "s" - it doesn't have that URI. The URI is "http://schemas.xmlsoap.org/soap/envelope/" . I'd also suggest avoiding XName.Get and just using XNamespace and the XName +(XNamespace, string) operator:
XNamespace s = "http://schemas.xmlsoap.org/soap/envelope/";
XElement body = xDoc.Descendants(s + "Body").FirstOrDefault();
