Question

输入

text = "Store Item Number (DPCI)=244-02-6685;Pop Musical Style=Arena Rock, Album Rock, Pop-Metal, Hard Rock, Hair Metal, Heavy Metal;Origin=Made in the USA or Imported;Record label=UNIVERSAL INT'L;...."

输出

(Store Item Number (DPCI),Pop Musical Style, Origin, Record label)

我需要一个正则表达式

Answer 1

\w+会匹配任何字词，但您正在尝试匹配特定的字符串。

(Store Item Number \(DPCI\)|Pop Musical Style|Origin|Record label)\=

Answer 2

您可以使用lookbehinds在Store Item Number (DPCI)和Pop Musical Style后抓取数据：

import re
text = "Store Item Number (DPCI)=244-02-6685;Pop Musical Style=Arena Rock, Album Rock, Pop-Metal, Hard Rock, Hair Metal, Heavy Metal;Origin=Made in the USA or Imported;Record label=UNIVERSAL INT'L;"
data = re.findall('(?<=Store Item Number \(DPCI\)\=)[\d\-]+|(?<=Pop Musical Style\=)[a-zA-Z\s,]+', text)

输出：

['244-02-6685', 'Arena Rock, Album Rock, Pop']

Answer 3

请参阅here示例：

^[^=]+|(?<=;)[^=]+

在;和=之间找到元素，或者从输入的开头开始并以=结尾的元素。

输出：['Store Item Number (DPCI)', 'Pop Musical Style', 'Origin', 'Record label']
