Check if XML Element exists

Question

How can someone validate that a specific element exists in an XML file? Say I have an ever changing XML file and I need to verify every element exists before reading/parsing

Answer 1

How about trying this:

using (XmlTextReader reader = new XmlTextReader(xmlPath))
{
    while (reader.Read())
    {
        if (reader.NodeType == XmlNodeType.Element)
        { 
            //do your code here
        }
    }
}
