Question

I have XML which looks something like this:

<?xml version="1.0" encoding="utf-8"?>
     <University>
          <Colleges>
            <College>
              <Id> Cambridge </Id>
              <Dept>
                <Id> Arts</Id>
              </Dept>
            </College>
            <College>
              <Id> Oxford</Id>
              <Dept>
                <Id> Philosophy </Id>
              </Dept>
            </College>
          </Colleges>
        </University>

I want to return the College based on the ID. In another scenario, I want to written just Id of the College.

I do not understand how to write LINQ statement to read Id directly. I can use Descendants() at every stage. But how to select the element which is deep inside the XML structure?

Answer 1

LINQ-XML,

XDocument doc = XDocument.Parse(xmlStr);
var results = doc.Root.Descendants("College")
              .Where(ele => ele.Element("Id").Value.Trim() == "Oxford");
