Dustin's Software Development Cogitations and Speculations: An OpenLaszlo RSS Reader Implementation:

In this blog entry, I demonstrate generation of a simple RSS Reader using OpenLaszlo. The world certainly doesn't need another RSS reader, so the purpose of this blog entry is to demonstrate some of the easy-to-use features of OpenLaszlo.

The RSS reader shown in this blog entry will focus on blogs hosted on Blogger (blogspot.com). There are two URLs one can use to access RSS feeds from blogs with the blogspot.com domain.

This OpenLaszlo example provide several observations about OpenLaszlo development. First, this example shows how easy it is to have OpenLaszlo access server-side XML resources using the tag:

request="true"
src="http://marxsoftware.blogspot.com/feeds/posts/default?alt=rss" />

The dataset tag example shown above uses only three lines to associate a handle/name with the dataset called "blogRssFeed", instructs OpenLaszlo to initialize the dataset immediately, and provides the URL from which to access the data. I could have added the attribute type="http" to explicitly instruct OpenLaszlo that this data is obtained from an HTTP connection (rather than from a file), but using "http://" in the src attribute did essentially the same thing.
