Definitely not elegant, and before my first cup o' coffee for the day has
sunk in, but how about something like:
>>> def convert(str):
... newstr = ''
... while str:
... if str.startswith(r'\x'):
... newstr += chr(string.atoi(str[2:4], 16))
... str = str[4:]
... newstr += str
... str = str[1:]
... return newstr
I don't think it would be efficient for long strings, but optimisation
is left as an exercise for the reader. :-)
