This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Two things that don't really solve your problem, but will definately help anyway...
First, edit your post and put the code and xml between the CODE brackets. It will make your post much easier to read.
