Debugger Preferences

To configure the Debugger preferences, open the Preferences dialog box (Options ⇒ Preferences) and go to XML ⇒ XSLT-FO-XQuery ⇒ Debugger.

The following options are available:

Show xsl:result-document output

If checked, the debugger presents the output of xsl:result-document instructions into the debugger output view.

Infinite loop detection

Enable this option to receive notifications when an infinite loop occurs during transformation.

Enable Saxon optimizations

This option is disabled by default and this means that the optimization level for the debugging process is set to zero. If it is enabled, the debugging process will use the optimization level from one of the following:

• The value specified in the Optimization level option in an associated XSLT transformation (or the same option in an associated XQuery transformation), if a transformation scenario is used in the debugging process.
• Otherwise, the value specified in the Optimization level option in the XSLT Saxon-HE/PE/EE preferences page (or the same option in the XQuery Saxon HE/PE/EE preferences page).

Maximum depth in templates stack

Allows you to set how many xsl:template instructions can appear on the current stack. This setting is used by the infinite loop detection.

Debugger layout

If you select the Horizontal layout, the stack of XML editors is presented on the left half of the editing area while the stack of XSL editors is on the right half. If you select the Vertical layout, the stack of XML editors is presented on the upper half of the editing area while the stack of XSL editors is on the lower half.

Debugger current instruction pointer

Allows you to set the background color of the current execution node, both in the document (XML) and XSLT/XQuery views.

XWatch evaluation timeout (seconds)

Allows you to specify the maximum time that Oxygen XML Developer allocates to the evaluation of XPath expressions while debugging.

Messages

Allows you to specify how to handle the debugging process when the source document involved in a debugging session is edited. You can choose one of the following:

• Ask me what to do
• Always stop the debugging session
• Never stop the debugging session
