Question

I have the following xml file:

<?xml version="1.0" encoding="utf-8"?>
<Cus>
  <Customer Location="NJ">
    <Male Value="True" />
    <Name Value="xxx" />
   </Customer>
  <Customer Location="NY">
    <Male Value="True" />
    <Name Value="yyy" />
   </Customer>
</Cus>

I am trying to query using the linq to xml inorder to get the value of male based on the customer location.

Here is the query:

  var Male = from e in doc.Descendants("Male")
             select new
             {
                 Male = e.Attribute("Value").Value.ToString()
             };

I am able to get the value of the male but i am confused how to get the name based on the location of the customer in the xml file.How to add a where condition in here which determines the location of the customer.I would appreciate if some one can guide me.

Per your question – to select the value of name based on location, you could use something like:

private string CountOfMales(XDocument doc, string locationToFilter)
{
  var selection = from customer in doc.Descendants("Customer")
                 .Where(c => c.Attribute("Location").Value == locationToFilter)
                 select new
                 {
                    MaleValue = customer.Element("Name").Attribute("Value").Value
                 };

                 return selection.FirstOrDefault().MaleValue;
}
