为什么TreeView node.text在C＃中显示奇怪的结构

Question

I have a treeview

Microsoft.Web.UI.WebControls.TreeView myTreeView = new Microsoft.Web.UI.WebControls.TreeView();
        myTreeView.Nodes.Clear();

And after populate data to the treeview I can show it nicely. However now I want to get the text in each branch of that tree (from root to parents to child in deepest level), and compare, if it is a certain name I will mark it as selected.

Microsoft.Web.UI.WebControls.TreeNodeCollection nodes = myTreeView.Nodes;
        foreach (Microsoft.Web.UI.WebControls.TreeNode n in nodes)
        {
            string nodetext = n.Text;
            if (nodetext == "Casting")
                myTreeView.SelectedNodeIndex = n.GetNodeIndex();
        }

However when I print nodetext , I get very confuse with its value:

<acronym Title='Casting, Closed Die Press Forging, Compression Moulding, Drop Forging, Injection Moulding, Moulding Compounds, Steel Atomisation, Transfer Moulding, Two Shot Moulding, Upset Forging, Vacuum Forming'>Casting, Moulding, Forming, & Forging</acronym>

While in display, it show a tree in this format:

Why the text has that format and how could I extract exactly the each branch name as in the image? And is it right to turn the selected feature as I do above ?

Answer 1

I found the answer. In other part of the code they append the nodetext for the tree by

return String.Format("<acronym Title='{0}'>{1}</acronym>",

that is why it has that format. To get the text, I just have to use regex:

//get text inside tag
            string regularExpressionPattern1 = @"<acronym .*?>(.*?)<\/acronym>";
            Regex regex = new Regex(regularExpressionPattern1, RegexOptions.Singleline);
            MatchCollection collection = regex.Matches(n.Text.ToString());
            Match m = collection[0];
            var stripped = m.Groups[1].Value;

Thanks for your attention! Hope that would help some one has something related.
