XmlDocumentSchema Class


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)


[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.UnmanagedCode)]
public sealed class XmlDocumentSchema : IDataSourceSchema

System_CAPS_pubmethodXmlDocumentSchema(XmlDocument, String)

Creates an instance of the XmlDocumentSchema class using a specified XmlDocument and an XPath string.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


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.


Returns a string that represents the current object.(Inherited from Object.)

The XmlDocumentSchema class is used by custom control designer components to list the structural elements of an XML document at design time. Use the XmlDocumentSchema class to populate lists of document elements to allow users to select document elements in UI features at design time.

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();

    // 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);
        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 = 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);
            // Select the parent of the current child
            CurNode = CurNode.Parent;
        // Select the parent of the current child
        CurNode = CurNode.Parent;
