Try This:
XDocument xmlDoc = XDocument.Load(CONFIG_FILE);
Dim ndSetting as XmlNodeList
ndSetting = XDocumentxmlDoc.GetElementsByTagName("Setting")
return ndSetting.Count
If you are going to search by the attribute change the
GetElementsByTagName to GetElementsById. Also if you have a number of
setting elements you can search by using the index ex. ndSetting(0)
Hope this helps,
