Overview

Returns the value of the attribute.

Imagine this time HTML element with a datetime attribute:

<time datetime="2019-07-01">...</time>

YAML usage example:

selectors:
  link:
    selector: time
    extractor: attribute
    attribute: datetime

Would return:

'2019-07-01'

In case you’re extracting a date or a time, do not forget to parse it during post processing with AttributePostProcessors::ParseTime.
