Thanks for the quick start. It is sooo fast to get started using this software. I wish the docs were clearer on that because most people want to dive in and start using it and worry about Twisted later. This post shows how easy it is!
One thing: if you want to click by partial text you should use
//a[contains('partial text',text() )]
as the Xpath expression, and it works like a charm.
sorry I was wrong with my XPath expression too, haven't figured it out yet.
