C# check an element exists while using LINQ to XML

Question

OK, bit of a random question, but the best way to do this is to just add the code, you\'ll be able to see what I mean straight away:

XML:

Answer 1

Should also be able to clean this kinda stuff up with extensions, something like..

public string Element_valStr(XElement xElm, string xName)
{
    if (xElm.Element(xName) == null) return string.empty;
    return xElm.Element(xName).Value;
}

and then just:

var superType = (from c in linquee.Descendants("customer")  
                  where (c.Element_valStr("SuperType") == "1")
                  select c).ToList();
