@fabaff, what do you think about adding support for pseudo-attribute “@” to return the tag itself ?

              """Return the state of the device."""
              return self._state
          
          
def _extract_value(self):
              """Parse the html extraction in the executor."""
              raw_data = BeautifulSoup(self.rest.data, "html.parser")
              _LOGGER.debug(raw_data)
          
          
    try:
                  if self._attr is not None:
                      value = raw_data.select(self._select)[self._index][self._attr]
                  else:
                      tag = raw_data.select(self._select)[self._index]
                      if tag.name in ("style", "script", "template"):
                          value = tag.string
                      else:
                          value = tag.text
              except IndexError:
                  _LOGGER.warning("Index '%s' not found in %s", self._attr, self.entity_id)
                  value = None
              except KeyError:

Something like:

        if self._attr == "@":
            value = raw_data.select(self._select)[self._index]
        elif self._attr is not None:
            value = raw_data.select(self._select)[self._index][self._attr]
        ...

This way, we could get svg or canvas and convert into an image.
