Vincent,

Try reading the xml schema into a DataSet, then you can just iterate through the column names to build your TreeView. This should get you started:

DataSet ds = new DataSet()
ds.ReadXml("MyXMLFile.xml", XmlReadMode.ReadSchema);

TreeView oTree = new TreeView();
TreeNode oNode;

// First add the Root Node
TreeNode RootNode = new TreeNode();
RootNode.Text = "Column Names";
oTree.Nodes.Add(RootNode);
oTree.ExpandAll();

for (int i=0; i < ds.Tables[0].Columns.Count; i ++)
{
    node = new TreeNode();
    node.Text = ds.Tables[0].Columns[i].ColumnName;
    RootNode.Nodes.Add(node);    
}
