Yes and yes. I'm currently using D1 but with view to D2 am having a peek at it's libs. I can see why std.xml in D2 is slow, and would not be surprised if buggy as well; it is quite disgusting code that's been hacked together without any real rhyme or reason. So guess I'll be writing my own stuff and leveraging on C libs where possible. Got Expat parser running with D without too much trouble. Thanks for comment grauzone. -- Justin Johansson
