What we want to do is take some representative example of an RSS feed, and get that header title, link and last build date information, then a few "items", with their title, link and publication dates. However, in an RSS feed, the ones we are going to look at are the ones that are certain to be there, and will have the information we want for a simple RSS skin.
It should be noted that there can be MANY other tags in a feed. This is followed by a series of one or more item entries, each of which has its own set of title/description/link/pubDate tags. Īs you can see, the pattern is that there is a header section which contains "tags" for the title, description, link and lastBuildDate of the overall feed. Here is some text containing an interesting description. While there are differences between the RSS and Atom standards, which we will touch on a bit later, let's use a simple RSS output to outline how they are laid out. RSS and Atom feeds follow certain patterns that make them fairly easy to parse. A great deal of additional help is available at Regular Expression Options. This guide is not intended as a general purpose tutorial for the WebParser measure, nor does it attempt to explore all that regular expressions can do. One of the most common uses of the WebParser measure in Rainmeter is to create a skin to parse and display information from an RSS or Atom feed.
