    ``[<taskname>#group.<groupnr>]``
    ","
    Get the contents from groupnr after processing received data.

    NB: The regular expression parsen uses 0-based group numbers (where most other regex parsers use 1-based group numbers!)
    "
    "
    ``[<taskname>#next.<groupvalue>]``
    ","
    Get the value of the next group that holds ``<groupvalue>``.

    Example:

    Regular expression: ``((node)=(%d+);?)((weight)=(%d+);?)((temp%d?)=(%-?%d+);?)((rssi)=(%-?%d+);?)``

    Received data: ``node=1;weight=40;temp1=20;rssi=-30``

    This will result in these groups:

    .. list-table::
        :widths: 20, 50, 200
        :header-rows: 1

        * - Group
          - Data
          -
        * - 0
          - node=1
          -
        * - 1
          - node

        * - 2
          - 1

          - weight=40

        * - 4
          - weight

        * - 5
          - 40
          -
        * - 6
          - temp1=20
          -
        * - 7
          - temp1
          -
        * - 8
          - 20
          -
        * - 9
          - rssi=-30
          -
        * - 10
          - rssi
          -
        * - 11
          - -30
          -

    Requesting ``[SerialProxy#next.weight]`` will return the value ``40``.
