Chapter 5. XSLT Debugger
Overview
The <oXygen/> plugin adds two perspectives into Eclipse. The first is the standard editing perspective
that provides general features and functions for the development of XML documents and other programming languages. The second is the Debugger perspective. The Debugger perspective is started by clicking the <oXygen/> XSLT Debugger button located on the perspective toolbar or selecting the
<oXygen/> XSLT Debugger from Window->Open Perspective->Other. To switch back to Editor perspective simply click the <oXygen/> XML button that is adjacent to the <oXygen/> XSLT Debugger
button on the perspective toolbar or select <oXygen/> XML from Window->Open Perspective->Other.
Users can toggle between Debugger and Editor modes as required by clicking either buttons.
This chapter explains the Debugger mode functionality, which provides a rich set of features for development, testing and solving of XSL problems, including:
