re.sub and empty groups

Hi! I'm trying to do a search-replace in places where some groups are optional... Here's an example: re.match(rImage:([^\|]+)(?:\|(.*))?, Image:ola).groups() ('ola', None) re.match(rImage:([^\|]+)(?:\|(.*))?, Image:ola|).groups() ('ola', '') re.match(rImage:([^\|]+)(?:\|(.*))?,
