I would like to know if it is possible to retrieve from a wikipedia page only the main description and, if it is available, the image.
For example I would like to get only the main description and the image of the U2 band from http://en.wikipedia.org/wiki/index.html?curid=52780. How can I do this? I looked on the Wikipedia API (http://en.wikipedia.org/w/api.php) but I haven't found nothing that feet my needs.
It would be great if there is a web service that retrieve an XML/JSON object with this data

Hope to hear from you soon!

regards,
Marco
