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. 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"] � r ���r )r r r s r � remove_quotesr/ ? s � � �Q�4��"��:�r c �l �� | r | dd� �n|� � � �d� �D � � ��fd�}|S )aK 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 Nc � � g | ] \ }}||f�� S r r )�.0�k�vs r � <listcomp>z"with_attribute.<locals>.<listcomp>� s � � &� &� &���1�a��V� &� &� &r c �� �� �D ]e\ }}||vrt | |d|z � � �|t j k r8|| |k r,t | |d� ||| |� � � � ��fd S )Nzno matching attribute z+attribute {!r} has value {!r}, must be {!r})r �with_attribute� ANY_VALUEr )r r �tokens�attrName� attrValue�attrss �r �pazwith_attribute.<locals>.pa� s� �� �#(� � � �H�i��v�%�%�$�Q��+C�h�+N�O�O�O��N� 4�4�4���9I�Y�9V�9V�$���A�H�H� �&��"2�I�� �� � �� � r )�items)�args� attr_dictr= r< s @r r7 r7 P s_ �� �r � "��Q�Q�Q�������!�!�� &� &�� &� &� &�E� � � � � � �Ir � c �P � |rd� |� � 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. 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 <div> 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:: 1 4 0 1 0 1 4 0 1 0 1,3 2,3 1,1 z{}:class�classr )r r7 )� classname� namespace� classattrs r � with_classrG � s; � �H 1:�F� �!�!�)�,�,�,�w�I� � 3� 3�Y� � 2� 3� 3�3r N)rA )� exceptionsr �utilr r r& r+ r/ r7 �objectr8 rG � replaceWith� removeQuotes� withAttribute� withClass�matchOnlyAtColr r r �<module>rP s� �� '� &� &� &� &� &� � � � � � � � � � � � � � �4 � � �&� &� &�"� � �"L� L� L�^ "�6�8�8�� �%4� %4� %4� %4�R � � � � � � � �"���r
