I came with the idea of this booklet thank to Peter Kenny that kindly answered a question on the Pharo mailing-list. To help, Peter showed to a Pharoer how to scrap a web site using XPath. In addition, some years ago I was maintaining Soup a scraping framework because I was scraping magic web sites and I wanted an application to manage my magic cards. Since then I always wanted to try XPath and in addition I wanted to offer this booklet to Peter. Why because I asked Peter if he would like to write something and he told that he was at a great age where he would not take any commitment. I realised that I would like to get as old as him and be able to hack like a mad in Pharo with new technology. So this booklet is a gift to Peter, a great and gentle Pharoer. Stef
