Detailed Description

Token for matching strings that match a given regular expression.
Defined with string specifying the regular expression in a form recognized by the inbuilt Python re module.
If the given regex contains named groups (defined using C{(?P<name>...)}), these will be preserved as 
named parse results.

Example::
    realnum = Regex(r"[+-]?\d+\.\d*")
    date = Regex(r'(?P<year>\d{4})-(?P<month>\d\d?)-(?P<day>\d\d?)')
    # ref: http://stackoverflow.com/questions/267399/how-do-you-match-only-valid-roman-numerals-with-a-regular-expression
    roman = Regex(r"M{0,4}(CM|CD|D?C{0,3})(XC|XL|L?X{0,3})(IX|IV|V?I{0,3})")

Constructor & Destructor Documentation

◆ __init__()

def __init__ (   self,
  pattern,
  flags = 0 
)
The parameters C{pattern} and C{flags} are passed to the C{re.compile()} function as-is. See the Python C{re} module for an explanation of the acceptable patterns and flags.
