如果你想使用正则表达式，你可以在一个组中捕获4968 (\d+) . "category_path":\["XXX\d+"(?:,"XXX\d+"){2},"XXX(\d+)"(?:,"XXX\d+")*\] 解释 "category_path":\[ 逐字匹配 "XXX\d+" 匹配数字模式而不昏迷 (?:,"XXX\d+"){2} 用逗号重复数字模式2次 "XXX(\d+)" 匹配 "XXX 捕捉一组中的一个或多个数字 (\d+) 匹配一个" (?:,"XXX\d+")*\] 将图案匹配零次或多次，然后结束 ]
(\d+)
"category_path":\["XXX\d+"(?:,"XXX\d+"){2},"XXX(\d+)"(?:,"XXX\d+")*\]
"category_path":\[
"XXX\d+"
(?:,"XXX\d+"){2}
"XXX(\d+)"
"XXX
(?:,"XXX\d+")*\]

尝试正则表达式： category_path":\[(?:"[X]+\d+",){3}"[X]+\K\d+ 演示
category_path":\[(?:"[X]+\d+",){3}"[X]+\K\d+
