Add elements to XDocument after LINQ Query

Question

I have the following XML LINQ query from my XDocument.

var totals = (from x in MyDocument.Descendants("TOTALS") select x).FirstOrDefault();

Once I have found my totals node I need to add some elements to that node and push that change to the XDocument.

Answer 1

Hi there.

you can use AddAfterSelf() to add new nodes against totals. Those changes will automatically get attached to the main XDocument, since totals is referencing an XElement inside the document.

Answer 2

So just make the change to the returned node... unless you clone it, it will still be part of the document.

Btw, your query expression isn't adding anything - simpler code would be:

var totals = MyDocument.Descendants("TOTALS").FirstOrDefault();

Answer 3

totals.Add(new XElement("NewNode", "New node value"));
