Download an RSS feed

Overview

There are many different formats within the RSS world, meaning that a static approach to RSS parsing is problematic. By using DISE Parser we can customize a feed parsing. Shipped with DISE Parser is an RSS download example which can serve as a starting point.

Setup

• Download, install and start Parser.
• Select File > Import.
• Go to the Samples directory and select the RSS.dpmodifiers file.
• Right click on the Download the RSS Feed (XML) modifier and select Settings.
• Write in the URL to the RSS feed that you want to process.
• Click Ok.
• Click Test.
• Take a look at the output file, located in your "Public\Documents\DISE Parser" folder in a file called "rss_output.txt".

Customization

The RSS (XML) data in the feed is run through something called XSL, which is a language to extract and restructure XML data.

With a little knowledge about XSL you can modify the file "rss_news.xsl" to have it include images, or to change the order the fields in the feed will appear.
