Select specific TreeNode to create XmlNode

[jotaefe]

Hi everyone,

After visiting and using plenty of your solutions exposed in this great website, I've finally got across a problem that I can't find a solution anywhere.

I have a TreeView that is populating a XML file that looks like this:

<commandset>
  <commandgroup name="Initialization">
    <command name="Reset" id="1">
      ...
    </command>
    <command name="Reset" id="2">
      ...
    </command>
    <command name="Init" id="3">
      ...
    </command>
  </commandgroup>
</commandset>
 

So when I populate the TreeView, I only display the "name" attributes.

My problem starts when I try select one "command" node in the TreeView to extract the data from the XML (and at the end reflect the changes back to the original XML).

To select the XmlNode, I am creating an string with the path to the TreeNode "command" with a function that looks like this:

 
private string GetTreeNodePathExpresion()
        {
            string expr = null;
            string myNode = treeView1.SelectedNode.Text;
            expr = "/commandset/command [@name='" + myNode + "']";
 
            return expr;    
        }
 

but as you can see in the XML, there are several commands with the same name, and this will always find the first XmlNode that fits the string path pattern.

Is there any way I can identify the TreeNodes using a unique ID or something similar?

Thanks.

If I could I'd give you an award for best noob first post.

You give them id attributes, can you not use those?

Maybe I didn't explain myself properly, but thanks for the nomination anyway.

I already found a solution:

During the population of the TreeView, when adding a new TreeNode, I am adding the "command" IDs attributes' values to the each "command" by using the Tag property. I've used this:

treeNode.Tag = xmlNode.Attributes["id"].Value;

So when I select any "command" node from the TreeView, I can check its Tag and chose the appropiate xml node.

There might be other solutions.

So your problem is solved then?

Yes, thanks.
