Overview

Returns the value of the href attribute. It always returns absolute URLs. If the extracted href value is a relative URL, it prepends the channel’s URL.

Imagine this a HTML element with a href attribute:

<a href="/posts/latest-findings">...</a>

YAML usage example:

channel:
  url: http://blog-without-a-feed.example.com
  ...
selectors:
  link:
    selector: a
    extractor: href

Would return:

'http://blog-without-a-feed.example.com/posts/latest-findings'
