# DTD editor

After you have created or imported a DTD, you can open it in the DTD editor (by double-clicking it in the Navigator view), a tool for viewing and editing DTDs. You can use the DTD editor to perform a variety of tasks such as creating, editing, and deleting DTD elements, attributes, entities, notations, and comments

Before you can perform any of these tasks, you must create a DTD and open it in the DTD editor. After you open the DTD, you can use the Outline view to create nodes and the Properties view to provide details about the nodes.

Note: In the Outline view, you can either work in default mode (all nodes appear in the order you added them to the DTD in) or group the DTD nodes into the following logical groups: notations, entities, elements, and other, by clicking the Group items logically button .
