LINQ to XML extract nested elements

Question

I\'m new to LINQ and XML parsing and rather new to C# programming. For the following XML structure, I\'m trying to extract the nested elements:

Answer 1

You can do it this way using linq:

var result = from p in xmlDoc.Descendants("person")
             from a in p.Descendants("address")
             where p.Element("personNumber").Value == "2" 
             select new 
                 { 
                   City = a.Element("city").Value, 
                   Location = a.Element("location").Value 
                 };

Answer 2

Sth like the following should work:

XDocument xmlDoc = XDocument.Load(@"mypath\persons.xml");

var q = from e in xmlDoc.Descendants("person")
        where e.Element("personNumber").Value == "2"
        let address = e.Descendants("address")
        from a in address
        select new {
           city = a.Element("city").Value,
           location = a.Element("location").Value
        };

With the sample xml provided in the OP the above linq query produces the following result:

[0] = { city = "XXX", location = "1" }
[1] = { city = "YYY", location = "2" }
