How can I grab all the child elements in XML?

From this XML response: http://www.dreamincode.net/forums/xml.php?showuser=335389

I want to grab all of the users friends. I need to grab all of the information from the friends. Usually with the help I've been given I would use the unique ID to grab each, but since each us开发者_运维知识库ers doesn't have the same friends it has to be dynamic and I can't hard code anything.

Would anyone please share some XDocument magic?

You can get all <user> elements in the <friends> element from the XML document like this:

var url = "http://www.dreamincode.net/forums/xml.php?showuser=335389";
var doc = XDocument.Load(url);
var friends = doc.Element("ipb").Element("profile")
                 .Element("friends").Elements("user");

// Or if you don't want to specify the whole path and you know that
// there is only a single element named <friends>:
var friends = doc.Descendant("friends").Elements("user");

Then you can use LINQ to process the collection. For example, to create a IEnumerable<string> with the names of all frineds, you could write:

var names = from fr in friends 
            select fr.Element("name").Value;

If you needed unique ID, you could read the <id> element in a similar way (if it is an integer, you could also parse it using Int32.Parse for example...)

you can probably use XPath query

the examples uses JScript but it is also supported in .NET
