现有独立正则 #

• 设备型号匹配正则（包含device_model和data9字段）：

  (?:device_model = \['?|data9 = \['|, ')([^'\],\r\n]*)(?=.*\r?\n(?:[ \t]*\[.*\r?\n)*?[ \t]*)
  

• 版本号匹配正则：

  (?:current_version = ')([^'\],\r\n]*)(?=.*\r?\n(?:[ \t]*\[.*\r?\n)*?[ \t]*)
  

错误的合并尝试 #

尝试合并成单个正则以同时捕获设备型号和对应版本号，但表达式报错“Your regular expression does not match the subject string”：

(?:device_model = \['?|data9 = \['|, ')([^'\],\r\n]*)(?=.*\r?\n(?:[ \t]*\[.*\r?\n)*?[ \t]*\[(?::current_version = ')(.*))

修正方案 #

你的合并正则有两处关键错误：

1. 冗余添加了\[和::，导致无法匹配到current_version行
2. 正向预查的逻辑没有正确关联到目标版本号的捕获

正确的合并正则如下：

(?:device_model = \['?|data9 = \['|, ')([^'\],\r\n]*)(?=.*\r?\n(?:[ \t]*.*\r?\n)*?[ \t]*current_version = '([^'\],\r\n]*))

修改说明 #

• 移除了错误的\[和::，直接匹配current_version = '前缀
• 调整预查内的匹配逻辑，用(?:[ \t]*.*\r?\n)*?非贪婪匹配设备型号行和版本号行之间的任意内容
• 第二个捕获组([^'\],\r\n]*)直接捕获版本号内容，确保与对应设备型号关联

该正则会为每个设备型号（包括data9中的值）返回两个捕获组：组1是设备型号，组2是对应的版本号。
