Removing a Node


Note		Before you can remove a node, you must delete any links to that node. See Removing Source-Target Map.

To remove a node from the target structure:

1. Remove any links to the node you want to remove from the target structure. See Removing Source-Target Map if you need help with this step.

2. Select the node and press the Delete key.

Alternative: Right-click the node and select Remove Node from the shortcut menu.

Setting a Text Value

You can set text values for target structure elements and attributes. You might want to do this if you are composing an XQuery with an element or attribute that requires a fixed value, instead of using a value gathered from an input XML document.

Here is the XQuery code Stylus Studio generates for the Title element when a text value is specified for it:


<Book> <Title>Confederacy of Dunces</Title> </Book>

Stylus Studio displays a red letter T for nodes for which you define a text value: .

To set a text value for a target structure node:

1. Right-click the node for which you want to set the text value.

The shortcut menu appears.

2. Select Set Text Value from the shortcut menu.

The Value dialog box appears.

3. Type the string you want to use as the text value and click OK.
