The iNews “interface” http://www.leonbloom.com
Not really an interface at all but a working example of how the iNews API can be used to build a web application.
In this example there are three files that are displayed in three frames.
Frame 1 is an OPML file:http://www.leonbloom.com/inews/iopml.opml?func=f (This file lists the urls of all of the RSS feeds)
Frame 2 is a RSS file: http://www.leonbloom.com/f/eaf89bc6d77cda68ba16.xml
Frame 3 is an Item from an RSS feed: http://www.leonbloom.com/g/e9aa81282916509a2a24.html
The OPML file source, found at: http://www.leonbloom.com/inews/iopml.opml?func=f
The RSS feed source:
Creating a REST Request
iNews Web Services are all REST services. That means you can easily construct request URLs that will work in your browser, on the command line, and in your code. For our example, we'll construct a query to return the access times of a particular item in an RSS feed. See the web search documentation to understand the details of this service.
General format of URL construction
The REST interface to the access XML
http://www.leonbloom.com/a?u=
Example of using a real URL in the REST request:
http://www.leonbloom.com/a?u=http%3A//news.bbc.co.uk/go/rss/-/2/hi/business/6400789.stm
Returned XML
