Breakpoints can be set in XSLT/XQuery documents and XML documents in
XSLT/XQuery debugging sessions.
To insert a breakpoint, follow these steps:
Click the line where you want to insert the breakpoint in the XML source
document or the XSLT/XQuery document.
You can only set breakpoints on the XML source in XSLT or XQuery
debugging sessions.
Breakpoints are automatically created on the ending line of a start tag,
even if you click a different line.
Click the vertical stripe on the left side of the editor
panel or select Create Breakpoint
(Shift+F7) from the Edit > Breakpoints menu.
Once you insert a breakpoint, it is automatically
added to the list in the Breakpoints view and you can edit its
associated condition. A breakpoint can have an associated break condition
that represents an XPath expression evaluated in the current debugger context. In order to be
processed, their evaluation result should be a boolean value. A breakpoint with
an associated condition only stops the execution of the Debugger if the breakpoint
condition is evaluated as true.
