Hi people, I have to sort some elements that have the following content: <art>1.1</art> <art>1</art> <art>2</art> <art>2.1.1</art> <art>2.1</art> and the order should be 1 - 1.1 - 2 - 2.1 - 2.1.1 What method should I use? because the value that I've to use for sorting has a hierarchical meaning.. Any idea? Thanks!! Esteban
