Hi! I want to replace some seqs. in a html. Let: a- b = ab
but: xxx - b must be unchanged, because it is not word split. I want to search and replace with re, but I don't know how to neg. this set ['\ \n\t']. This time I use full set without these chars, but neg. is better and shorter. Ok, I can use [^\s], but I want to know, how to neg. set of chars. sNorm1= '([^[\ \t\n]]{1})\-\<br\ \/\>\n' - this is not working. Thanks for the help: dd sNorm1= '([%s]{1})\-\<br\ \/\>\n' c = range(0, 256) c.remove(32) c.remove(13) c.remove(10) c.remove(9) s = ["\\%s" % (hex(v).replace('00x', '')) for v in c] sNorm1 = sNorm1 % ("".join(s)) print sNorm1 def Normalize(Text): rx = re.compile(sNorm1) def replacer(match): return match.group(1) return rx.sub(replacer, Text) print Normalize('a -<br />\nb') print Normalize('a-<br />\nb') sys.exit() -- http://mail.python.org/mailman/listinfo/python-list
