Question : LINQ Query not yielding expected results

Hello Everyone.

So I have the following XML:



with the following query:

String number = "22222";

      XDocument Facility = XDocument.Load(facility.xml");
      var query =
      from
      cFa in Facility.Descendants("cofacility")
      where
      cFa.Element("facility").Element("company").Attribute("no").Value == number
      select cFa.Elements("facility").Elements("contact");

So what I am trying to get all the contacts in all the facilities that are part of a specific company number. So for example, if I ask for company "number" = 12345, I should get the following:

and when I use number = "55555" I should only get

However, my query does not give me a result when I use "55555" or "22222". What I am doing wrong? and how can I just the the values out instead of the entire XElement?

Thanks for you help.

Hi Kozela;

There are two ways to get the value of the attribute name. Both of these are in the code snippet below.

             // Get the Attribute name from within the query
XDocument Facility = XDocument.Load("facility.xml");
var query = from cFa in Facility.Descendants("cofacility").Elements("facility")
            from cNo in cFa.Elements("company")
            where cNo.Attribute("no").Value == number
            select cFa.Elements("contact").Attributes("name");

foreach (var q in query)
{
    foreach(string contact in q)
    {
        Console.WriteLine(contact.ToString());
    }
}


// Get the Attribute name after the query when you enumerate the query itself
XDocument Facility = XDocument.Load("facility.xml");
var query = from cFa in Facility.Descendants("cofacility").Elements("facility")
            from cNo in cFa.Elements("company")
            where cNo.Attribute("no").Value == number
            select cFa.Elements("contact");

foreach (var q in query)
{
    foreach (XElement contact in q)
    {
        Console.WriteLine(contact.Attribute("name").Value);
    }
}
