Answer 1

Reading an XML file into a string is simple:

string xml = File.ReadAllText(fileName);

The to access the content, you would read it into an XmlDocument:

XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);

Answer 2

using System.Xml.Linq;

// load the file
            var xDocument = XDocument.Load(@"C:\MyFile.xml");
// convert the xml into string (did not get why do you want to do this)
            string xml = xDocument.ToString();

Now, using xDocument, you can manipulate the XML & save it back -

           xDocument.Save(@"C:\MyFile.xml");
