Use ``with_attribute`` to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as ```` or ``
``. 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 = '''
