python中的多个正则表达式匹配

Question

I am new to regex in python, while the simple cases are a breeze, I am having troubles extracting multiple words from a string using. The string looks like this:

lyne = "| 0x008d | 2345| 0xe54b5b42 | 0520 | 0x02 GREEN| 4 RED |"

and access the different substrings between the | | using match.group

is there a way to do this...can anyone please help

Thanks

Answer 1

无需正则表达式：

substrs = [x.strip() for x in lyne.split('|') if x]

Answer 2

Any reason you can't just use lyne.split('|') which'll do it, otherwise use re.split() with the same thing...

If you really want a regexp (to match/find instead of split), then (stripping out spaces):

>>> re.findall(r'\|?\s*(.*?)\s*\|', lyne)
['0x008d', '2345', '0xe54b5b42', '0520', '0x02 GREEN', '4 RED']
