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

    Call ``withAttribute`` 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:`withClass`.

    To verify that the attribute exists, but without specifying a value,
    pass ``withAttribute.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 = makeHTMLTags("div")

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

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