Solution 2

C#

XmlDocument xdoc = new XmlDocument();
xdoc.LoadXml("Your XML here");
XmlNodeList xnodes = xdoc.SelectNodes("/Key");
int count = xnodes.Count;
foreach (XmlNode xnode in xnodes)
{
     // TODO: Implement your code here
}

Solution 3

You may use following xpath to get the count of 'Value' node in the xml.

XML

count(//Key/Value)

To get the number of child elements in a node, we may use following xpath.

XML

count(//Key/*)
