                LLWNameAttr

Known Subclasses:

Baseclass to hide pattern-matching of various element names. Subclasses must provide a .dec_pattern compiled regular expression defining a group "Name" that identifies the meaningful portion of the string, and a .enc_pattern that gives a format string to be used with "%" to reconstrct the full string.

This is intended to be used to provide the enc and dec functions for an attributeproxy instance.

Example:

>>> import re
>>> class Test(Element):
...     class TestName(LLWNameAttr):
...             dec_pattern = re.compile(r"(?P<Name>[a-z0-9_]+):test\Z")
...             enc_pattern = u"%s:test"
...
...     Name = attributeproxy(u"Name", enc = TestName.enc, dec = TestName)
...
>>> x = Test()
>>> x.Name = u"blah"
>>> # internally, suffix has been appended
>>> x.getAttribute("Name")
u'blah:test'
>>> # but attributeproxy reports original value
>>> x.Name
u'blah'
