The tree view in the Export Template view for XHTML represents a real-time DOM tree. Each XHTML element of the tree in the Header and Detail sections has a pop-up menu. The pop-up menu items perform DOM-based actions for modifying the structural layout of the XHTML document that will be generated. The menu options include:
Menu item |
DOM-based action |
|---|---|
Edit |
DOMNode::SetNodeName |
Add Child |
DOMNode::AppendChild |
Insert Before |
DOMNode::InsertBefore |
Delete |
DOMNode::RemoveChild |
Edit allows changing the label of the tree view item representing the XHTML element name. All element items that display no attributes, as well as literal text nodes selected in the tree view, can also be edited with a single mouse-click or with the shortcut key F2. Add Child allows appending an entity as a last child. The submenu option DataWindow Control Reference invokes a dialog containing a filtered list box of Column, Computed Field, and Text controls for user selection. Control references can also be added to empty attribute values or element contents using drag-and-drop from the existing Control List View. DataWindow Expressions can also be added using the existing dialog. DataWindow column references (in the form of expressions) can also be added using drag-and-drop from the Column Specification View. Tree view items, except the <form> element, can also be deleted with the Delete key.
The remaining context menu items invoke dialogs that allow overriding presentational and functional specifications of each element. These include:
Style declarations
Element attributes
JavaScript event handlers
The dialogs first display these specifications as they would be generated at runtime by default. The painter gets these from the XML Web Generator in DWE in real-time, read-only display on one half of the dialog. Within input field(s) on the other half of the dialog, the developer can override these specifications at the atomic declaration or attribute level. This includes resetting included declarations/attributes, setting declarations/attributes not included, or removing declarations/attributes. These change specifications will then persist in the XHTML export template, and be applied to the default presentation generated by the XML Web Generator at runtime.
