Count child nodes on XDocument

Question

Is there a way to count child nodes on an XDocument?

I looked for a count method or property and could not find one.

Thanks Leo

Answer 1

var doc = XDocument.Load(fileName);
int descendantsCount = doc.Descendants().Count(); // counts ALL descendants elements
int childrenCount = doc.Root.Elements().Count(); // counts direct children of the root element

Answer 2

Alternatively ... if you know that the name of the elements are never going to change and they always exist,

XDocument xD = XDocument.Load(XmlFullFileName);
XElement xE_ParameterSets = xD.Root.Element("Report").Element("ParameterSets");
int index = ((IEnumerable<XElement>)xE_ParameterSets.Elements()).Count();
