Watching Particular Variables

Use the Watch window to monitor particular variables. To display the Watch window, click Watch in the Stylus Studio tool bar. This button is active when Stylus Studio suspends processing because it reached a breakpoint. Stylus Studio displays the Watch window only when processing is suspended.

Enter the names of the variables you want to watch. You can enter as many as you like. In a Java program, you can double-click a symbol and drag it to the Watch window to enter it as a variable you want to watch. When Stylus Studio suspends processing, it displays the current values for any variables listed in the Watch window. You can expand and collapse complex structures as needed.

Another way to obtain the value for a variable is to hover over the symbol in your stylesheet or Java program. Stylus Studio displays a pop-up box that contains the current value.

During XSLT debugging, you can enter XPath expressions in the Watch window fields. Stylus Studio uses the current context to evaluate these expressions, and displays the results with the same kind of interface Stylus Studio uses for nodeList and node variables.
