Overview

Returns HTML code as Markdown formatted String. Before converting to markdown, the HTML is sanitized with SanitizeHtml. Imagine this HTML structure:

<section>
  Lorem <b>ipsum</b> dolor...
  <iframe src="https://evil.corp/miner"></iframe>
  <script>alert();</script>
</section>

YAML usage example:

selectors:
  description:
    selector: section
    extractor: html
    post_process:
      name: html_to_markdown

Would return:

'Lorem **ipsum** dolor'
