insert data from xml page into mysql database

[maria zotou]

Hello, I have an xml page from which I want to retrieve its data and store it on a mysql database. the problem is that I don't want the xml page to be stored in my computer (in other words to have a static content) but I want to retrieve the data from the page's url, as the xml page is actually an xml feed from a website and therefore changes its information occasionally. So I want every time that this xml page refreshes, to refresh my database as well. Does anyone know how something like this can be done?Thank you in advance!
