Python正则表达式从字符串中的锚点提取上一组/下一组

Question

Given a string containing four values:

1) Vehicle model        <- any number of alpha-numeric words
2) Engine description   <- one word before the next value:
3) Power output         <- \d+KW
4) Optional keywords    <- any number of alpha-numeric words

For example:
1-SERIE 118I 105KW EFF.DYN. BUSINESS LINE
MINI CLUBMAN 1.6T 128KW COOPER S
TWINGO 1.2 55KW

How to extract these into Python variables using re?

I think the simplest approach is to first find the power output (an anchor point), and then match the previous word to find the engine description , and then match everything before that to retrieve the model . Also match everything after the power output to find the optional keywords .

I feel I need to do something with (?<= ..) but I can't get it to work..

Slightly modified from Matt G. (added named groups and matches all optional keywords):

^(?P<model>([\S\s]+?))(?= \S+(?= \d+KW)) (?P<engine>(\S+))(?=(?= \d+KW)) (?P<kw>(\d+))KW(?P<keywords>(?<=KW)\s?(.*))

Answer 1

Try Regex: ^([\\S\\s]+?)(?= \\S+(?= \\d+KW)) (\\S+)(?=(?= \\d+KW)) (\\d+)KW(?: ([^\\s]+))*
