To get all name nodes use XPath expression /Names/Name. To get only male names (to select all nodes with specific XML attribute) use XPath expression /Names/Name[@type='M'].

 

XmlDocument xml = new XmlDocument();
xml.LoadXml(myXMLDocPath);  //Path of XML file

XmlNodeList xnList = xml.SelectNodes("/Names/Name[@type='M']");

foreach (XmlNode xn in xnList)
{
  Console.WriteLine(xn.InnerText);
}

 

The output is:
