If you export your WordPress blog, it is delivered to you as an RSS feed that holds all of the blog's entries, pages and comments. WordPress makes use of five namespaces and calls the format WordPress eXtended RSS (WXR). I'm working on a Java application that converts a WXR file into a set of static HTML pages.

The exodus of users away from Twitter and Reddit has led many of those information refugees to discover the joy of subscribing to feeds in a reader. RSS and Atom feeds are an enormous open decentralized network that can never be ruined under new ownership -- because there's no owner.

Tara Calishain of ResearchBuzz has written a 4,000-word introduction to RSS for people who are new to the world of feeds:

I could not do ResearchBuzz without RSS feeds. They're invaluable. And I think if you learn more about them, you'll appreciate why I consider RSS the most underrated tech on the Internet. That's what this article is about: I'm going to explain what RSS feeds are, show you how to find them, go over some of the RSS feed readers available, and, finally, list several tools and resources you might find useful on your journey.

... I follow over a thousand RSS feeds which deliver information to me throughout the day. Do you think I could visit a thousand websites a day to check for new information? Even if I tried to visit a thousand a week that would be over 142 websites a day. Assuming it took me two minutes to visit a site and check for new content, I would spend over 4.5 hours a day just visiting websites.

Do you see why I'm so grateful for RSS?

Calishain, who was blogging before Netscape created RSS in 1999, covers a lot more than the basics, showing how to find hidden feeds on websites, check a bunch of feeds for freshness and create keyword-based feeds to search sites like Google News, Hacker News and WordPress. Even experienced readers of readers will learn new things, and there's a collection of nine handy RSS Gizmos she has developed.

On that subject, Calishain just began programming a year ago:

In spring 2022 I decided to find out if I could really learn JavaScript after being diagnosed as autistic. (I'm a high school dropout and didn't think I could learn something like programming.)

I CAN! And I LOVE IT!

Welcome to the not-so-secret society of programmers, Tara! Please slow down a little. You're making the rest of us look bad.

There are a lot of libraries for processing XML data with Java that can be used to read RSS feeds. One of the best is the open source library XOM created by the computer book author Elliotte Rusty Harold.

As he wrote one of his 20 books about Java and XML, Harold got so frustrated with the available Java libraries for XML that he created his own. XOM, which stands for XML Object Model, was designed to be easy to learn while still being strict about XML, requiring documents that are well-formed and utilize namespaces in complete adherence to the specification. (At the RSS Advisory Board, talk of following a spec is our love language.)

XOM was introduced in 2002 and is currently up to version 1.3.9, though all versions have remained compatible since 1.0. To use XOM, download the class library in one of the packages available on the XOM homepage. You can avoid needing any further configuration by choosing one of the options that includes third-party JAR files in the download. This allows XOM to use an included SAX parser under the hood to process XML.

Here's Java code that loads items from The Guardian's RSS 2.0 feed containing articles by Ben Hammersley, displaying them as HTML output:

// create an XML builder and load the feed using a URL
Builder bob = new Builder();
Document doc = bob.build("https://www.theguardian.com/profile/benhammersley/rss");
// load the root element and channel
Element rss = doc.getRootElement();
Element channel = rss.getFirstChildElement("channel");
// load all items in the channel
Elements items = channel.getChildElements("item");
for (Element item : items) {
  // load elements of the item
  String title = item.getFirstChildElement("title").getValue();
  String author = item.getFirstChildElement("creator",
    "http://purl.org/dc/elements/1.1/").getValue();
  String description = item.getFirstChildElement("description").getValue();
  // display the output
  System.out.println(">h2>" + title + ">/h2>");
  System.out.println(">p>>b>By " + author + ">/b>>/p>");
  System.out.println(">p>" + description + ">/p>");

All of the classes used in this code are in the top-level package nu.xom, which has comprehensive JavaDoc describing their use. Like all Java code this is a little long-winded, but Harold's class names do a good job of explaining what they do. A Builder uses its build() method with a URL as the argument to load a feed into a Document over the web. There are also other build methods to load a feed from a file, reader, input stream, or string.

Elements can be retrieved by their names such as "title", "link" or "description". An element with only one child of a specific type can be retrieved using the getFirstChildElement() method with the name as the argument:

Element linkElement = item.getFirstChildElement("link");

An element containing multiple children of the same type uses getChildElements() instead:

Elements enclosures = item.getChildElements("enclosure");
if (enclosures.size() > 1) {
  System.out.println("I'm pretty sure an item should only include one enclosure");
}

If an element is in a namespace, there must be a second argument providing the namespace URI. Like many RSS feeds, the ones from The Guardian use a dc:creator element from Dublin Core to credit the item's author. That namespace has the URI "http://purl.org/dc/elements/1.1/".

If the element specified in getFirstChildElement() or getChild Elements() is not present, those methods return null. You may need to check for this when adapting the code to load other RSS feeds.

If the name Ben Hammersley sounds familiar, he coined the term "podcasting" in his February 2004 article for The Guardian about the new phenomenon of delivering audio files in RSS feeds.
