Earlier this week I was struggling with an XSLT transformation. Usually it sort of works and requires some tweaking. But now I could not get it to work at all. I was doing the transformation from within a .Net control.
Googling for an XSLT debugger was quite surprising. It turns out that Visual Studio has an XSLT debugger! Since version 2005 if I am not mistaken. Wow!
So I fired up Visual Studio and started debugging. Within minutes I got it to work.
Just open an XML/XSLT file and go to the XML menu. There it should mention an option like XSLT debug. The rest is self explanatory.
