Creating Breakpoints in XSLT
Programs 
Use
You use breakpoints to stop the execution of the XSL transformation at a certain point in the transformation program. The XSLT debugger, in this case, interrupts the transformation immediately before the breakpoint line, that is, before a specific statement is called.
Prerequisites
Breakpoints can only be created for the source code of the XSLT program, not for the XML document.
Note that breakpoints can only be set for executable statements. Statements that cannot be executed include the following:
· End tags (example: </table>)
· Top-level statements (example: <xsl:template ... />). Top-level attributes are an exception.
Procedure
Creating Line Breakpoints
In the Transformation Editor, you can set a line breakpoint in change mode as well as in display mode. Proceed as follows:
1. In Transaction SE80, select the XSLT program that you want to examine and then start the Transformation Editor.
2. Place the cursor on the line in the source code where you want to set the breakpoint.
3.
Click the
icon in the application toolbar.
In the XSLT debugger, proceed as follows to set a line breakpoint:
1. Position the cursor on the line in the XSL source code display where you want to set a breakpoint.
2.
Double-click
the selected line or click the icon in the
application toolbar.
If the
selected line only contains a non-executable statement, the breakpoint is
automatically set in the next executable line. In this case, the system issues
an appropriate message in the debugger message line. If the line already
contains a breakpoint, the system deletes it.
The breakpoint line is always marked in yellow and the new line breakpoint is
included inbreakpoint list.
Creating Template Breakpoints
In debugging mode and in the transformation editor, you can stop the execution of the XML transformation at a particular template in an XSLT program.
To create a template breakpoint in the debugger:
1. In debugging mode, click the switch button Breakpoints to get to the breakpoint view.
2.
Choose 
Breakpoint.
The system displays a dialog box in which you can specify the breakpoint.
3. Choose Template and enter the name of the required template in the input field.
If you wish to create a line breakpoint at this point, choose Line and enter the appropriate line number in the input field.
4. Choose Continue to confirm your entries.
If your entries were correct, the new breakpoint will be added to the breakpoint list. If you have created a template breakpoint, the new breakpoint is not highlighted in color, contrary to the case for line breakpoints.
Creating Program Breakpoints
Using program breakpoints, you can start the debugger already when the XSLT program is started.
To create program breakpoints for the current XSLT program in the Transformation Editor:
...
1. Choose the menu function Utilities ® Set/Delete Breakpoint.
2. Choose the option Program Breakpoint in the displayed dialog box.
3.
Choose .
