正则表达式替换

Question

我有一个文件，并且该单词出现在该行的中间，基于从行的开头到模式匹配需要替换的单词。

示例行：

the browser separates off the name/value pairs and other information which is sent in the header and puts it in

在这里，我们需要找到单词other并从行的开头替换为other }的单词the

提前致谢。

Answer 1

use strict;
use warnings;

while(<DATA>) {  $_=~s/^((?:(?!other).)*)other//i;  print $_;  }

__DATA__
the browser separates off the name/value pairs and other information which is sent in the header and puts it in

输出：

 information which is sent in the header and puts it in
