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 ```` or ````.
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 = '''
Some text
1 4 0 1 0
1,3 2,3 1,1

'''
div,div_end = makeHTMLTags("div")
# only match div tag having a type attribute with value "grid"

Helper method for constructing grammars of expressions made up of
operators working in a precedence hierarchy. Operators may be unary
or binary, left- or right-associative. Parse actions can also be
attached to operator expressions. The generated parser will also
recognize the use of parentheses to override operator precedences
(see example below).
Note: if you define a deep operator list, you may see performance
issues when using infixNotation. See
:class:`ParserElement.enablePackrat` for a mechanism to potentially
improve your parser performance.
Parameters:
- baseExpr - expression representing the most basic element for the
nested
- opList - list of tuples, one for each operator precedence level
in the expression grammar; each tuple is of the form ``(opExpr,
numTerms, rightLeftAssoc, parseAction)``, where:
- opExpr is the pyparsing expression for the operator; may also
be a string, which will be converted to a Literal; if numTerms
is 3, opExpr is a tuple of two expressions, for the two
operators separating the 3 terms
- numTerms is the number of terms for this operator (must be 1,
2, or 3)
- rightLeftAssoc is the indicator whether the operator is right
or left associative, using the pyparsing-defined constants
``opAssoc.RIGHT`` and ``opAssoc.LEFT``.
- parseAction is the parse action to be associated with
expressions matching this operator expression (the parse action
tuple member may be omitted); if the parse action is passed
a tuple or list of functions, this is equivalent to calling
``setParseAction(*fn)``
(:class:`ParserElement.setParseAction`)
- lpar - expression for matching left-parentheses
(default= ``Suppress('(')``)
- rpar - expression for matching right-parentheses
(default= ``Suppress(')')``)
Example::
# simple example of four-function arithmetic with ints and
# variable names
integer = pyparsing_common.signed_integer
varname = pyparsing_common.identifier
arith_expr = infixNotation(integer | varname,
[
('-', 1, opAssoc.RIGHT),
(oneOf('* /'), 2, opAssoc.LEFT),
(oneOf('+ -'), 2, opAssoc.LEFT),
])
arith_expr.runTests('''

prints::

closing delimiters ("(" and ")" are the default).
Parameters:
- opener - opening character for a nested list
(default= ``"("``); can also be a pyparsing expression
- closer - closing character for a nested list
(default= ``")"``); can also be a pyparsing expression
- content - expression for items within the nested lists
(default= ``None``)
- ignoreExpr - expression for ignoring opening and closing
delimiters (default= :class:`quotedString`)
If an expression is not provided for the content argument, the
nested expression will capture all whitespace-delimited content
between delimiters as a list of separate values.
Use the ``ignoreExpr`` argument to define expressions that may
contain opening or closing characters that should not be treated as
opening or closing characters for nesting, such as quotedString or
a comment expression. Specify multiple expressions using an
:class:`Or` or :class:`MatchFirst`. The default is
:class:`quotedString`, but if no expressions are to be ignored, then
pass ``None`` for this argument.
Example::
data_type = oneOf("void int short long char float double")
decl_data_type = Combine(data_type + Optional(Word('*')))
ident = Word(alphas+'_', alphanums+'_')
number = pyparsing_common.number

A set of Unicode characters, for language-specific strings for
``alphas``, ``nums``, ``alphanums``, and ``printables``.
A unicode_set is defined by a list of ranges in the Unicode character
set, in a class attribute ``_ranges``, such as::
_ranges = [(0x0020, 0x007e), (0x00a0, 0x00ff),]
A unicode set can also be defined using multiple inheritance of other unicode sets::
