Reading an XML From C#

[DarkLinux]

Hello,
I am trying to read from a XML file in C#. I have coded a waypoints system. I can save the waypoints in an XML file. My problem is I have little free time to work on it. I ran into a problem trying to read from my XML. Any help like examples to helpful links will suffice.

XML File

<?xml version="1.0"?>
<Path>
      <Name>SW Test</Name>
      <Nodes>
            <Node id="0" x="-8832.103" y="637.4868" z="0" />
            <Node id="1" x="-8832.148" y="637.5655" z="0" />
            <Node id="2" x="-8827.26" y="637.9915" z="0" />
            <Node id="3" x="-8822.965" y="637.6017" z="0" />
            <Node id="4" x="-8818.634" y="640.0749" z="0" />
            <Node id="5" x="-8814.84" y="639.9224" z="0" />
            <Node id="6" x="-8811.952" y="636.7586" z="0" />
            <Node id="7" x="-8811.789" y="631.8894" z="0" />
            <Node id="8" x="-8812.003" y="631.8409" z="0" />
            <Node id="9" x="-8818.141" y="628.4603" z="0" />
            <Node id="10" x="-8820.524" y="627.1432" z="0" />
      </Nodes>
      <Sellers>
            <Seller id="0" />
      </Sellers>
</Path>

This is the code I have come up with, it does not work.

           //* create an xml document object.
            XmlDocument xmlDoc = new XmlDocument(); 
            
           //* load the XML document from the specified file,
            xmlDoc.Load(@"C:\\xml2.xml"); 
            

            //* Get elements.
            XmlNodeList node = xmlDoc.GetElementsByTagName("Nodes");
            XmlNodeList seller = xmlDoc.GetElementsByTagName("Sellers");

            //* Display the results.
            for (int i = 0; i < 1000; i++)
            {
                OutPut("Node ID: " + node[i].InnerText);
            }
            OutPut("Seller ID: " + seller[0].InnerText);

I know it has something to do with the fact that node has 3 vars and I am only reading one. I just can figure it out.

Thanks for your help and time. +Rep to all that help!

Some dummy code..

public static List<Node> LoadFile(string filename)
{
	if (File.Exists(filename) == false)
		return false;

	XmlReader Reader = XmlReader.Create(filename);
	List<Node> NodeList = new List<Node>();
	while (Reader.Read())
	{
		if (Reader.NodeType != XmlNodeType.Element)
			continue;

		Node ParsedNode = new Node();
		int.TryParse(Reader.GetAttribute("id"), out ParsedNode.Id);
		float.TryParse(Reader.GetAttribute("x"), out ParsedNode.X);
		float.TryParse(Reader.GetAttribute("y"), out ParsedNode.Y);
		float.TryParse(Reader.GetAttribute("z"), out ParsedNode.Z);

		NodeList.Add(ParsedNode);
	}

	Reader.Close();
	return NodeList;
}

I would suggest using xml serialization. Since its based on your own format and everything - itd be way easier

If using .NET 3 or newer, you can use LINQ.

(from e in XElement.Load(filename).Descendants("Node")
                         let x = float.Parse(e.Attribute("x").Value)
                         let y = float.Parse(e.Attribute("y").Value)
                         let z = float.Parse(e.Attribute("z").Value)
                         select new Node(x, y, z)).ToList();

Obviously you'll want to fix the query, but that's just an example.

Thanks so much for the help! You have no idea how much this has helped.
