[Pyparsing] escape sequences in identifiers

[Diez B. R. <de...@we...>]

Hi,

I'm using pyparsing to parse CSS. Now I've encountered css-classes  
with dots in them the first time - so I need to extend my identifier  
definition to encompass backslash escapes.

This test-program illustrates my problem. Or at least some problem, my  
real code throws for the same testcase an exception:

======================================================================
ERROR: Tests that various parts of the grammer parse
----------------------------------------------------------------------
Traceback (most recent call last):
   File "/Users/deets/projects/privat/TurboGears/ablcssprocessor/tests/ 
test_parser.py", line 42, in test_subexpressions
     (r'foo\.bar', [r"foo\.bar"]),
   File "/Users/deets/projects/privat/TurboGears/ablcssprocessor/tests/ 
test_parser.py", line 27, in parse
     result = g.parseString(test, True).asList()
   File "/Users/deets/.virtualenvs2.5/cssprocessor/lib/python2.5/site- 
packages/pyparsing-1.5.2-py2.5.egg/pyparsing.py", line 1076, in  
parseString
     raise exc
ParseException: Expected end of text (at char 4), (line:1, col:5)

----------------------------------------------------------------------

Any suggestions how to deal with this? Thanks,

Diez
