正则表达式需要有两个条件结束条件

Question

我需要一个正则表达式来处理不同的终端条件，我的想法是这样的，但它不起作用

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

输入格式如下：

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

Answer 1

说明

^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

示例文本

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

样本匹配

• 捕获组0获取整个匹配
• 捕获组1只获取第一个引号中的值。
  • 如果值以: "结尾，后跟非]，则不包括:和尾随文本
  • 如果该值以: "]结尾，则:和尾随空格将包括在内

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

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

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