class Html2rss::ItemExtractors::Href
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'
