Question

How do you convert char to XElement.value from a XML file in WPF ? I've printed the tree elements, but not their values; I get the cannot convert from 'char' to 'System.Xml.Linq.XElement' argument. Perphaps i'm iterating the wrong type ?

Thank you

    public partial class MainWindow : Window
   {
    string file1 = System.IO.File.ReadAllText(@"H:\MpxWpfComponents.strings.xsd");
    string file2 = System.IO.File.ReadAllText(@"H:\MpxWpfComponents.bg.strings.xml");
    string file3 = System.IO.File.ReadAllText(@"H:\MpxWpfComponents.fr.strings.xml");

    public MainWindow()
    {
        InitializeComponent();
    }

    private void btnOpenFile_Click1(object sender, RoutedEventArgs e)
    {
        OpenFileDialog openFileDialog = new OpenFileDialog();
        openFileDialog.Filter = "XML files (*.xml)|*.xml|All files (*.*)|*.*";
        openFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

        if (openFileDialog.ShowDialog() == true)
        {
            foreach (string filename in openFileDialog.FileNames)
                listXML.Items.Add(Path.GetFileName(filename));
        }
        var xmlDoc = XDocument.Parse(file2);
        BuildTree(treeView.Items, xmlDoc.Elements().First());           
    }

    private void BuildTree(ItemCollection itemCollection, XElement xElement)
    {
        var item = new TreeViewItem() { Header = xElement.Name.LocalName };
        itemCollection.Add(item);
        foreach (var xElem in xElement.Elements())
        {
            BuildTree(item.Items, xElem);
        }

        item = new TreeViewItem() { Header = xElement.Value };
        itemCollection.Add(item);

        foreach (var xElem in xElement.Value)
        {
            BuildTree(item.Items, xElem);
        }
    }

The Value property returns the text contents of the element. You want to iterate through the element's child elements:

private void BuildTree(ItemCollection itemCollection, XElement xElement)
{
    var item = new TreeViewItem() { Header = xElement.Name.LocalName };
    itemCollection.Add(item);
    foreach (var xElem in xElement.Elements())
    {
        BuildTree(item.Items, xElem);
    }

    item = new TreeViewItem() { Header = xElement.Value };
    itemCollection.Add(item);

    foreach (var xElem in xElement.Elements()) //<---
    {
        BuildTree(item.Items, xElem);
    }
}
