C# XPathNavigator doesnt like attributes and wont find the data

[WestyCHC]

Morning all from a newbie.

I have recently written an automation program (my first ever program) for testing and now I am trying to read XML data and assign the values to variables (rather than Excel). Using XPathNavigator I managed to read some of the data, but in order to do this I had to manually remove the attributes from the Parent Nodes. Going forward this isnt an option as we may be reading and running hundreds of files a day and so I ask for your help.

Here is my code:

XPathDocument xpd = new XPathDocument(ReqFile);
            XPathNavigator xpn = xpd.CreateNavigator();
            XPathNodeIterator xpi = xpn.Select("/System/Case");
 
            Console.WriteLine("0, Current name = " + xpi.Current.Name);
 
            while (xpi.MoveNext()) // each testcase node
            {
                Console.WriteLine("1, Current name = " + xpi.Current.Name);
 
                XPathNodeIterator tcChild = xpi.Current.SelectChildren(XPathNodeType.Element);  
                while (tcChild.MoveNext()) // each part (<inputs> and <expected>) of <testcase>
                {
                    Console.WriteLine("2, tcChildName value = " + tcChild.Current.Value + ", tcChildName = " + tcChild.Current.Name);
 

This will read and therefore write to the output window the following XML file:
[XML]
<?xml version="1.0" encoding="utf-8"?>

but it wont read:

Obviously I have missed out a lot of the XML files as they are huge but they are all correct in that they have closing tags.

I have tried changing my code:
XPathNodeIterator xpi = xpn.Select("/System[*]/Case[*]");
OR
XPathNodeIterator xpi = xpn.Select("/System[@*]/Case[@*]");

but to no avail. I cannot work out why one file can be read whilst the other cant. The only difference being is the attributes. It may well be a simple answer but after 2 days staring at this and scouring the internet I cannot fathom it out. Any help will be appreciated.

Using C# Visual Studio Express 2008 on a Windows XP Machine.
