Answer 1

You can get the value of a particular element like,

 var fareIndex = XmlDoc.SelectSingleNode("/root/itinerary/FareIndex").InnerText;

If you want to get the list of all elements that come under root/itinerary -

  XmlNodeList xnList = XmlDoc.SelectNodes("/root/itinerary/*");

You can use System.Xml.Linq.XElement to parse an xml:

XElement xRoot = XElement.Parse(xmlText);
XElement xItinerary = xRoot.Elements().First();
// or xItinerary = xRoot.Element("itinerary");

foreach (XElement node in xItinerary.Elements())
{
    // Read node here: node.Name, node.Value and node.Attributes()
}

If you want to use XmlDocument you can do like this:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xmlText);

XmlNode itinerary = xmlDoc.FirstChild;
foreach (XmlNode node in itinerary.ChildNodes)
{
    string name = node.Name;
    string value = node.Value;

    // you can also read node.Attributes
}
