How can I retrieve the text from a specific element of this XML?

I am trying to figure out Xmldocument for the first time. I cannot figure out how to pull a single element out of an xml file. I need to find a certain url in the xml document and determine if the user has access to that url and delete the xml related to that article if the user does not.

Sorry about the messy XML I am pulling directly from a the string where it is stored. I left off the rest of the xml as it is VERY long. How will I access the information I want?

using LINQ's XDocument:

from off the top of my head, syntax may be a little off

XDocument doc = XDocument.Parse(yourString);

string url = (from x in doc.Descendants("url") select x.Value).FirstOrDefault();
