NET class libraries are very rich and you rarely have to use any third party tools for simple tasks like parsing RSS feeds. Such tools were very useful in the past before the convenient classes and methods were provided by the. There are several other ways to parse RSS files like the RSS Reader project in the Codeplex. RSS Reader - Third Party Utility to Parse RSS Files NET Framework 3.5 or above, you may use the SyndicationFeed class as well. You may manually change the syntax or use one of the C# to VB.NET convert tools.

The above code sample is in C#, but if you are looking for VB.NET examples, it is quite easy to convert the code in to VB.NET. Return the string that contain the RSS items return rssContent.ToString() RssContent.Append( " " + title + " " + description) String description = rssSubNode != null ? rssSubNode.InnerText : " " RssSubNode = rssNode.SelectSingleNode( " description") String link = rssSubNode != null ? rssSubNode.InnerText : " " RssSubNode = rssNode.SelectSingleNode( " link") String title = rssSubNode != null ? rssSubNode.InnerText : " " XmlNode rssSubNode = rssNode.SelectSingleNode( " title") Iterate through the items in the RSS file foreach (XmlNode rssNode in rssNodes) StringBuilder rssContent = new StringBuilder() XmlNodeList rssNodes = rssXmlDoc.SelectNodes( " rss/channel/item") The docker image will contain the environment of our app, in this case it’s Node.js.XmlDocument rssXmlDoc = new XmlDocument() In this case, it’s a name, description and what docker image to use. This acts as a sort of description of our app. The final piece was to create an app.json file. So with that, our Procfile looks exactly like this: web: node index.js This file contains some process types, and there’s a few, but in this case we only need the web process type to fire up our little Express app. To specify what command to run (in this case node index.js), I created a new file called Procfile in the root of my project.

Next was some configuration - I needed to tell Heroku how to run the app.
#JAVASCRIPT RSS FEED READER EXAMPLE FREE#
For me, I chose Heroku because of their free plan and integration with GitHub. You might already have a hosting plan where you can fire up a PHP script to do the same thing. You could do this with any language you fancy. Running node index.js and visiting in your browser then should return a bounty of data. The format of the XML file is specified via the RSS specification. An RSS document is an XML file which can be used to publish blog entries and news. Eclipse is used as the Java IDE and Java7 is used. PORT || 5000 Ĭonst feedRequests = FEED_LIST. This tutorial explains how to read and create RSS feeds with Java. const express = require ( 'express' ) Ĭonst Parser = require ( 'rss-parser' ) Ĭonst PORT = process. I created a little project that uses Express to respond to a GET request which returns my feed data. It does exactly what I was looking for you pass a URL to a feed, and get JSON back.
How do I get that JSON, though? After a couple of keystrokes on NPM I found rss-parser. I like JavaScript, and having a JSON object with data in it that I can iterate over is ideal. I don’t need a way to share them I can use something like Buffer. I don’t need a ‘save for later’ feature I can use Instapaper for that. I know how that comes across, and the more I re-type and re-read that line the more I hate myself, but I don’t need a lot of features I want to have a list of feeds, a list of articles for a feed, and a view for a single article. So simple in fact, that I figured I’d build my own. However, I’m a simple guy with simple needs. They all work pretty well, and I’d happily recommend a good few of them. There’s a whole heap of services and apps out there for collating your own personalised list of RSS feeds, and discovering new ones.
