    Helper method for common parse actions that simply return
    a literal value.  Especially useful when used with
    :class:`transform_string<ParserElement.transform_string>` ().

    Example::

        num = Word(nums).set_parse_action(lambda toks: int(toks[0]))
        na = one_of("N/A NA").set_parse_action(replace_with(math.nan))
        term = na | num

        OneOrMore(term).parse_string("324 234 N/A 234") # -> [324, 234, nan, 234]

    Helper parse action for removing quotation marks from parsed
    quoted strings.

    Example::

        # by default, quotation marks are included in parsed results
        quoted_string.parse_string("'Now is the Winter of our Discontent'") # -> ["'Now is the Winter of our Discontent'"]

        # use remove_quotes to strip quotation marks from parsed results
        quoted_string.set_parse_action(remove_quotes)
        quoted_string.parse_string("'Now is the Winter of our Discontent'") # -> ["Now is the Winter of our Discontent"]

    Helper to create a validating parse action to be used with start
    tags created with :class:`make_xml_tags` or
    :class:`make_html_tags`. Use ``with_attribute`` to qualify
    a starting tag with a required attribute value, to avoid false
    matches on common tags such as ``<TD>`` or ``<DIV>``.

    Call ``with_attribute`` with a series of attribute names and
    values. Specify the list of filter attributes names and values as:

    - keyword arguments, as in ``(align="right")``, or
    - as an explicit dict with ``**`` operator, when an attribute
      name is also a Python reserved word, as in ``**{"class":"Customer", "align":"right"}``
    - a list of name-value tuples, as in ``(("ns1:class", "Customer"), ("ns2:align", "right"))``

    For attribute names with a namespace prefix, you must use the second
    form.  Attribute names are matched insensitive to upper/lower case.

    If just testing for ``class`` (with or without a namespace), use
    :class:`with_class`.

    To verify that the attribute exists, but without specifying a value,
    pass ``with_attribute.ANY_VALUE`` as the value.

    Example::

        html = '''
            <div>
            Some text
            <div type="grid">1 4 0 1 0</div>
            <div type="graph">1,3 2,3 1,1</div>
            <div>this has no type</div>
            </div>

        '''
        div,div_end = make_html_tags("div")

        # only match div tag having a type attribute with value "grid"
        div_grid = div().set_parse_action(with_attribute(type="grid"))
        grid_expr = div_grid + SkipTo(div | div_end)("body")
        for grid_header in grid_expr.search_string(html):
            print(grid_header.body)

        # construct a match with any div tag having a type attribute, regardless of the value
        div_any_type = div().set_parse_action(with_attribute(type=with_attribute.ANY_VALUE))
        div_expr = div_any_type + SkipTo(div | div_end)("body")
        for div_header in div_expr.search_string(html):
            print(div_header.body)

    prints::

        1 4 0 1 0

        1 4 0 1 0
        1,3 2,3 1,1

    Simplified version of :class:`with_attribute` when
    matching on a div class - made difficult because ``class`` is
    a reserved word in Python.

    Example::

        html = '''
            <div>
            Some text
            <div class="grid">1 4 0 1 0</div>
            <div class="graph">1,3 2,3 1,1</div>
            <div>this &lt;div&gt; has no class</div>
            </div>

        '''
        div,div_end = make_html_tags("div")
        div_grid = div().set_parse_action(with_class("grid"))

        grid_expr = div_grid + SkipTo(div | div_end)("body")
        for grid_header in grid_expr.search_string(html):
            print(grid_header.body)

        div_any_type = div().set_parse_action(with_class(withAttribute.ANY_VALUE))
        div_expr = div_any_type + SkipTo(div | div_end)("body")
        for div_header in div_expr.search_string(html):
            print(div_header.body)

    prints::
