Regular Expression question

[李政]

I'm sorry! I mean pattern is an argument of the function, in this case, how I process special charactors.
        patter = 'www.'                   # not this 
      if re.compile(pattern).match(string) is not None:
          ......
   
  but not:
   
      if re.compile(r'www.').match(string) is not None:           
  or
      if re.compile('www\.').match(string) is not None: 
   
  , how you process special characters, like dot.

if you want to parse HTML, use an HTML parser. if you want to parse 
sloppy HTML, use a tolerant HTML parser:
