Hey Chris, I believe I’m getting closer and closer to appreciating the beauty and the simplicity of the concepts behind greedy and non-greedy.
Patrick’s guidance yesterday worked perfectly and I customized his regex to suit my specific needs. I’ll continue working on simplifying things. Simplicity is VERY powerful. I hope everyone else in our group will benefit from these conversations. Thanks for your great tutorial and example.
