正则表达式需要有两个条件结束条件

Question

我需要有一个处理不同最终条件的正则表达式，我的想法是这样的，但它不起作用

re.findall(r'(?<=tests\[")(.*)((?="\])|(?=:)', input_string])

输入采用以下格式：

tests["Status code: " +responseCode.code] = responseCode.code === 200;
tests["Schema validator GetTerminalInitEventForHarewareIds"] = tv4.validate(data, schema);

Answer 1

描述

^tests\["(.*?)(?::\s*"\s*[^\]]|"\])

此正则表达式将执行以下操作：

• 要求字符串以tests["
开头
• 匹配第一个双引号内的子字符串

示例文字

tests["Status code: " +responseCode.code] = responseCode.code === 200;
tests["Schema validator GetTerminalInitEventForHarewareIds"] = tv4.validate(data, schema);

样本匹配

• 捕获组0获得整场比赛
• 捕获组1只获取第一个引号内的值。
  • 如果值以: "后跟非]结尾，则不包含:和尾随文字
  • 如果值以: "]结尾，则包含:和尾随空格

MATCH 1
1.  [7-18]  `Status code`

MATCH 2
1.  [78-129]    `Schema validator GetTerminalInitEventForHarewareIds`

MATCH 3
1.  [169-224]   `Schema validator GetTerminalInitEventForHarewareIds: `
