Hi there,
imagine your file name is "xmlNav.xml"
One way to show it, is as following:

...
using System.Data.SqlClient;
...

DataSet myXML = new DataSet();
myXML.ReadXml("xmlNav.xml");

StringBuilder myXMLstr = new StringBuilder();
foreach (DataColumn peClmn in myXML.Tables["PlugInEvent"].Columns)
   if (peClmn.Caption != "PlugInEvent_Id")
      myXMLstr.Append(peClmn.ToString() + ": " + myXML.Tables["PlugInEvent"].Rows[0][peClmn] + "\r\n");
            
myXMLstr.Append("Must Implement:" + "\r\n");

string mySpc = new string(' ', 6);
foreach (DataColumn iTypeClmn in myXML.Tables["MustImplementType"].Columns)
   if (iTypeClmn.Caption != "MustImplementTypes_Id")
      myXMLstr.Append(mySpc + iTypeClmn.ToString() + ": " + myXML.Tables["MustImplementType"].Rows[0][iTypeClmn] + "\r\n");

MessageBox.Show(myXMLstr.ToString());

You can also use XML Stream Reader.

Hope it helps
