Dynamic Parameters

For websites with similar structures but varying content based on a parameter in the URL or headers, you can use dynamic parameters.

Solution

Section titled “Solution”

You can add dynamic parameters to the channel and headers values. This is useful for creating feeds from structurally similar pages with different URLs.

channel:
  url: "http://domainname.tld/whatever/%<id>s.html"
headers:
  X-Something: "%<foo>s"

You can then pass the values for these parameters when you run html2rss:

Terminal window
html2rss feed the_feed_config.yml --params id:42 foo:bar

Explanation

Section titled “Explanation”
  • The %<param>s syntax in the URL and headers is a placeholder for dynamic parameters.
  • You provide the actual values for these parameters at runtime using the --params option.
  • This allows you to reuse the same feed configuration for multiple similar pages or APIs.
