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

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();
