.NET Framework 4.5
Represents the structure, or schema, of an XmlDocument. This class cannot be inherited.
Namespace: System.Web.UI.Design
Assembly: System.Design (in System.Design.dll)
The XmlDocumentSchema type exposes the following members.
| Name | Description | |
|---|---|---|
 | XmlDocumentSchema | Creates an instance of the XmlDocumentSchema class using a specified XmlDocument and an XPath string. |
| Name | Description | |
|---|---|---|
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetViews | Gets an array containing information about each child node starting at the node identified by the xPath parameter in the constructor, or each child node starting at the document root if the xPath parameter is empty. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
The following code example uses an XmlDocumentSchema object to display the structure of an XML document in a TreeView control.
// This method fills a TreeView Web control from an XML file. public void FillTreeView(TreeView treeVw, string fileName) { // Get a reference to the current HttpContext HttpContext currentContext = HttpContext.Current; int i, j, k; TreeNode CurNode, NewNode; // Create and load an XML document XmlDocument XDoc = new XmlDocument(); XDoc.Load(currentContext.Server.MapPath(fileName)); // Get a map of the XML Document XmlDocumentSchema xSchema = new XmlDocumentSchema(XDoc, ""); // Get a list of the root child views IDataSourceViewSchema[] RootViews = xSchema.GetViews(); // Add each child to the TreeView for (i = 0; i < RootViews.Length; i++) { NewNode = new TreeNode(RootViews[i].Name); treeVw.Nodes.Add(NewNode); CurNode = treeVw.Nodes[i]; // Get a list of children of this child IDataSourceViewSchema[] ChildViews = RootViews[i].GetChildren(); // Add each child to the child node of the TreeView for (j = 0; j < ChildViews.Length; j++) { NewNode = new TreeNode(ChildViews[j].Name); CurNode.ChildNodes.Add(NewNode); CurNode = CurNode.ChildNodes[j]; // Get a list of children of this child IDataSourceViewSchema[] ChildVws = ChildViews[j].GetChildren(); // Add each child to the child node for (k = 0; k < ChildVws.Length; k++) { NewNode = new TreeNode(ChildVws[k].Name); CurNode.ChildNodes.Add(NewNode); } // Select the parent of the current child CurNode = CurNode.Parent; } // Select the parent of the current child CurNode = CurNode.Parent; } }
