Selectors

Selectors can be used to install custom selector engines. See Working with selectors for more information.

selectors.register(name, **kwargs)#

  • name <str> Name that is used in selectors as a prefix, e.g. {name: 'foo'} enables foo=myselectorbody selectors. May only contain [a-zA-Z0-9_] characters.
  • content_script <bool> Whether to run this selector engine in isolated JavaScript environment. This environment has access to the same DOM, but not any JavaScript objects from the frame's scripts. Defaults to false. Note that running as a content script is not guaranteed when this engine is used together with other registered engines.
  • path <Union[str, pathlib.Path]> Path to the JavaScript file. If path is a relative path, then it is resolved relative to the current working directory.
  • script <str> Raw script content.
