I have seen various content sites including an 'XML button', which can presumably be used to pull their content into my own site. But how exactly does one do this or do I need some other tool for this purpose? FYI, I use FrontPage 2003 to create my sites. Thanks for any pointers in the right direction.
The XML tag can mean any number of things - it may be an RSS 1.0 feed, an RSS 2.0 feed, an Atom XML feed, or a custom XML feed. Usually it's an RSS feed, but "usually" can change. Gecko tribe makes a php application called Carp that you can use for RSS feeds, and has an additional application called Grouper for atom and other XML feeds. There's also an open source project called MagPie RSS that many people like. I prefer Carp over MagPie, but that's just me. MagPie can do everything you need and it's free. GeckoTribe's products have free and paid versions. There are also any number of other commercial products out there for other platforms, including a few javascript solutions. You can also read this content using various news readers designed to read RSS and Atom feed content.
Thanks for the comments above. I went ahead and downloaded CaRP (the free version) and it tested fine. But I still cannot figure out how I can get the feed from a content provider (e.g. http://www.articledepot.co.uk/list-Food.htm) into my own site. How do I get the exact path of the RSS / XML feed file of the content provider?
There are auto-discovery utilities out there, but that requires that content providers adhere to standards that enable auto-discovery. For the most part, blog software comes out of the box with rss feeds in standard locations with some hidden text that will help out make auto-discovery work, but you won't see a lot of custom applications that do so. If you are searching for rss feeds, try out places like syndic8, blog explosion, etc. There are a lot of topical rss directories out there.
The RSS path of http://www.articledepot.co.uk/list-Food.htm is http://www.articledepot.co.uk/rss/Food-new.xml for the Latest Submits or http://www.articledepot.co.uk/rss/Food-random.xml for a Random 5 which is updated daily You can find the path by clicking on the XML button and viewing the feed
