[英]Regular expression to extract words before a slash
I'd like to extract the two words FIRST and SECOND from the phrase below, i've tried with this regex, to get the word before the slash but it doesn't work : / btw it's on python: 我想从下面的短语中提取两个单词FIRST和SECOND,我已经尝试过使用此正则表达式,使其在斜杠前得到,但它不起作用:/ btw它在python上:
import re
data = "12341 O:EXAMPLE (FIRST:/xxxxxx) R:SECOND/xxxxx id:1234"
data2 = "12341 O:EXAMPLE:FIRST2:/xxxxxx) R:SECOND2/xxxxx id:1234"
result = re.findall(r'[/]*',data)
result2 = re.findall(r'[/]*',data2)
print result,result2
Try 尝试
result = re.findall(r'\w+:?(?=/)',data)
Explanation: 说明:
\w+ # Match one or more alphanumeric characters
:? # Match an optional colon
(?=/) # Assert that the next character is a slash
If you don't want the colon to be part of the match (your question is unclear on this), put the optional colon into the lookahead assertion: 如果您不希望冒号成为比赛的一部分(您的问题尚不清楚),请将可选冒号放入超前断言:
result = re.findall(r'\w+(?=:?/)',data)
