This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
My past experiences with XSLT have been a mixture of both crazed frustration and joy when I eventually stumble on a solution. To my mind it seems that tool support - with a decent debugger - for XSLT development is a must. Are there any open source/shareware/freeware tools that you can recommend to me ?
I agree that the choice of IDEs for XSLT development is not as wide as for other languages. I've had pleasant experience with XSLT-process mode for Emacs (http://xslt-process.sf.net); it has breakpoints, step-by-step execution, variable lookup etc. Some commercial solutions also exist. However, in my opinion, the side-effect-free nature of XSLT makes traditional debugging techniques less of a necessity; in my view, you can do very well with only a text editor with a good XML editing support. My book, however, has a chapter on various kinds of XML/XSLT software where I tried to cover different scenarios and approaches.
