Overview

Returns the URI as String. If the URL is relative, it builds an absolute one with the channel’s URL as base.

Imagine this HTML structure:

<span>http://why-not-use-a-link.uh </span>

YAML usage example:

selectors:
  link:
    selector: span
    extractor: text
    post_process:
      name: parse_uri

Would return:

'http://why-not-use-a-link.uh'
