Well now thanks to radio's web services I can filter all my RSS feeds and only look at those items that match a keyword.
<%params = {"cancer"}; xml.rpc ("147.188.64.44", 5335, "radio.rssSearch", @params)%>
The params = {"cancer"} tells the service to only display those feed items that contain the keyword "cancer". Try this service for yourself on your own site. Try other health-related keywords. All my feeds are health and health education related.
If you like this you can have it for your own site.
If you're not ready to install the web service on your own site then try it via mine! Copy and paste the following macro in a new weblog post in your site:
<%params = {"deganwy"}; xml.rpc ("147.188.64.44", 5335, "radio.picturegallery", @params)%>
The params= {"deganwy"} tells the service to display all those pictures in my site with a filename containing "deganwy". To view all pictures just leave the params field empty thus params = {""}. This is a nice example of how services allow you to both collaborate and interoperate with other weblogs. We could even build a meta picture gallery!
You can download the web service and install it on your own site by right clicking and saving the following file into your Radio:Web Services directory.
Replace the 147.188.64.44 in the macro above with the IP address of the machine running your copy of Radio and bingo! Your own pictures web service.
By all means open the script and look at how it works. There's a commented-out script step that shows you how to log the web service hits. You will find the script in the Radio.root database at user.betty.rpcHandlers.radio.picturegallery.
