Basic data source editing can be done directly in the Data Source Tree Dialog Bar. The Edit Node, Insert Attribute and Insert Element dialogs appear when right-clicking on elements or attributes in the Data Source Dialog Bar.
The functionality of these dialogs will be described below.
This allows editing of the name and value of an XML node in the tree.
To display the dialog: right-click on a node in the Data Source dialog bar and select Edit.
The Value text box only effects attributes and the reserved keyword text(), which marks plain text nodes.

This allows inserting attributes in the data source.
To display the dialog: right-click on a node in the Data Source dialog bar and select Add Attribute. Then, type a name and a value for the attribute.

Use this dialog to insert elements in the data source.
To display the dialog: right-click on a node in the Data Source dialog bar and select Add Element. Then, type a name and a value for the element.

Note: If more complex editing is required, click on the Edit Data Source Icon (the folder) to open the XML for editing in a new window. See the Data Source Dialog Bar page for more information.
