The XWatch view shows XPath expressions evaluated during the debugging process. Expressions are evaluated dynamically as the processor changes its source context.
When you type an XPath expression in the Expression column, Oxygen XML Developer supports you with syntax highlight and content completion assistance.
The XPath watch view
| Column | Description |
|---|---|
| Expression | XPath expression to be evaluated (XPath 1.0 or 2.0 compliant). |
| Value | Result of XPath expression evaluation. Value has a type (see the possible values in the section Variables View). For Node Set results, the number of nodes in the set is shown in parenthesis. |
Important: Remarks about working with the XWatch view:
- Expressions referring to variables names are not evaluated.
- The expression list is not deleted at the end of the transformation (it is preserved between debugging sessions).
- To insert a new expression, click the first empty line of the Expression column and start typing. As an alternative, right click and select the Add action. Press (Enter) on the cell to add and evaluate.
- To delete an expression, click on its Expression column and delete its content. As an alternative, right click and select the Remove action. Press (Enter) on the cell to commit changes.
- If the expression result type is a Node Set, click it (Value column) and its value is displayed in the Nodes/Values Set view.
- The Copy, Add, Remove and Remove All actions are available in every row's contextual menu.
