我想出了以下正则表达式来找到类似的行：
^.*?(_t91(.*?)1 0 2 5).*?$
基本上我必须将数字5更改为数字6，我正在尝试使用以下正则表达式：
\1t91\21 0 2 6
结果是一行以't91'开头并以更换数字结束，但随后重复2-3次（即：2 6 0 226 0 0 36t91等）
你们有什么想法吗？正则表达式对我来说仍然是一个谜。
提前致谢。
答案 0 :(得分：0)
从我看到你试图将5替换为特定环境中的整个单词。
要匹配整个单词，您需要\b（单词边界），以便不更改55之类的值。
要在整行上只替换一次，可以使用正则表达式
^(.*?_t91.*?1\s+0\s+2\s+)5(\b.*?)$
|-----first group------| | 2|
并替换为${1}6${2}（虽然\16\2也适用于此处。）
如果在一行中有多个这样的值，请使用
(_t91.*?1\s+0\s+2\s+)5\b
并替换为${1}6。
