Answer 1

Look at the XML:

<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
...

That's the Envelope element in the namespace with URI "http://www.w3.org/2003/05/soap-envelope".

Now look at your code:

doc.Element("Envelope")...

That's looking for an Envelope element that's not in any namespace. You should specify the namespace - and the namespaces of the other elements you're looking for:

XNamespace env = "http://www.w3.org/2003/05/soap-envelope";
XNamespace responseNs = "http://www.sap.com/SBO/DIS";
XDocument doc = XDocument.Parse(xmlstring);
var result = doc.Element(env + "Envelope")
    .Element(env + "Body")
    .Element(responseNs + "AddResponse")
    .Element(responseNs + "PickListParams")
    .Element(responseNs + "Absoluteentry").Value;

Answer 2

You can use Descendants too. Descendants finds children at any level.

var result = doc.Element(env + "Envelope")
    .Element(env + "Body")
    .Descendants(responseNs + "Absoluteentry").Value;
