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.
This book is aimed specifically at developers with little or no understanding of XML. There are no prerequisites for the book. It starts at the beginning and shows you how to work with XML in web applications so it would be a good introduction.
