XNamespace myNamespace = "some namespace";
var query = from response in xmlDoc.Elements(myNamespace + "PersonsMin")

you've forgotten to add the XML namespace to the query

XNamespace myNamespace = "some attribute";<br />
var query = from response in xmlDoc.Elements(myNamespace + "PersonsMin")<br />
