This example of web page scraping no longer works because the Met site has changed . Originally the page depended on a Javascript version of the data which was messy to parse but the html page is now scrapable again.
This case study is however quite extensive and in addition to page-scraping, it uses job-scheduling to cache the XML forecast, generates a KML map and provides an SMS service .
At present the case study is hidden under the httpclient entry but if redeveloped, should be in a section on projects with an intro to explain what concepts it uses.
However we have a number of case where xquery is used for web scrapping and these need consolidating .
