get all the elements that have a particular element name

Question

My xml looks like this:

<nodes><skus><sku>abc</sku><sku>def123</sku></skus></nodes>

I want to get all the elements with the name 'sku'

I have a XDocument already loaded with the xml.

List<XElement> elements = doc.Elements.Where( ??? )

or would I just do:

doc.Elements("sku")

?

I don't want this to return an error if there are no elements.

Answer 1

You want a nodelist of the elements of that tag name:

XmlNodeList nodes = doc.GetElementsByTagName("sku");

Answer 2

Elements() only returns the direct children of a node.

doc.Descendants("sku");

should do the trick. It searches along the descendants axis.

Answer 3

Hi there.

static void Main(string[] args)
        {
            var g = XDocument.Parse("<nodes><skus><sku>abc</sku><sku>def123</sku></skus></nodes>");

            var t = from e in g.Descendants("sku")
                    select e;

        }

EDIT: I started this example, but got interrupted - I'm determined to get this code on SO even if it kills me!!

Cheers. Jas.
