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 term[1, ...].parse_string("324 234 N/A 234") # -> [324, 234, nan, 234] c � �� �gS �Nr )r r r �repl_strs �r �<lambda>z replace_with.<locals>.<lambda>< s �� �H�:� r r )r* s `r � replace_withr, . s �� � &�%r c � � |d dd S )a# Helper parse action for removing quotation marks from parsed quoted strings.

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 Nc � �� �D ]N \ }}||vrt | |d|z � �|t j k7 s�.|| |k7 s�7t | |d|�d|| �d|��� � y )Nzno matching attribute z attribute z has value z , must be )r �with_attribute� ANY_VALUE)r r �tokens�attrName� attrValue�attrss �r �pazwith_attribute.<locals>.pa� s �� �#(� � �H�i��v�%�$�Q��+C�h�+N�O�O��N� 4� 4�4���9I�Y�9V�$��� �� �K��x�8H�7K�:�V_�Ub�c�� � r )�items)�args� attr_dict�k�vr9 r8 s @r r3 r3 P sG �� �r ��Q������!�� %� &���1�a��V� &�E� � �I�� 's �8c �. � |r|� d�nd}t di || i��S )a� Simplified version of :class:`with_attribute` when matching on a div class - made difficult because ``class`` is a reserved word in Python.
