Parsing RSS feeds and output HTML


In this recipe, we will use the curl and xml2 tools of Linux to parse the RSS feed.

Getting ready

  • You need to ensure that you have curl installed on your system
  • You need to ensure that you have xml2 installed on your system

How to do it…

We will provide a URL in curl, and using the xml2 tool, we will parse the RSS feed. Run the following command in your Terminal:

$ curl -sL https://imdb.com | xml2 | head

How it works…

We used xml2 and curl Linux tools to parse the XML RSS feed; xml2 converts XML document into text. In the output, each line is a key that is an XML path, and its value is separated by =.
