    r'''
    Return a list of parent lines (as text)  matching the regular expression
    ``parent_regex`` that have children lines matching ``child_regex``.

    config
        The configuration sent as text.

        .. note::
            This argument is ignored when ``config_path`` is specified.

    config_path
        The absolute or remote path to the file with the configuration to be
        parsed. This argument supports the usual Salt filesystem URIs, e.g.,
        ``salt://``, ``https://``, ``ftp://``, ``s3://``, etc.

    parent_regex
        The regular expression to match the parent lines against.

    child_regex
        The regular expression to match the child lines against.

    ignore_ws: ``False``
        Whether to ignore the white spaces.

    saltenv: ``base``
        Salt fileserver environment from which to retrieve the file. This
        argument is ignored when ``config_path`` is not a ``salt://`` URL.

    CLI Example:

    .. code-block:: bash

        salt '*' ciscoconfparse.find_lines_w_child config_path=https://bit.ly/2uIRxau parent_regex='ge-(.*)' child_regex='unit \d+'
