\1 matches an additional occurence of a text matched by an earlier part of the regex. Example: This regular expression: ([Cc][Aa][Ss][Ee]).*\1 would match a line such as Case matches Case but not Case doesn't match cASE. A regex can have multiple subgroups, so \2, \3, etc c...
先上需求和效果 替换之前: 替换之后: 要点 1.Ctrl+R 唤起此窗口 2.勾选 Regex (使用正则查找) 3.第一个输入框输入相应的正则表达式,无须添加//左右分解符,注意应该转义的部分需要替换的用括号包起来(跟用preg_match一样,第一个匹配内容用$1表示) 4.第二个框输入替换后的内容 5.点击 Replace all...猜...

在Java中,java.util.regex包定义了正则表达式使用到的相关类,其中最主要的两个类为:Pattern、Matcher: Pattern 编译正则表达式后创建一个匹配模式; Matcher 使用Pattern实例提供的正则表达式对目标字符串进行匹配,是真正影响搜索的对象。。 1、Pattern类常用方法 public static Patter... ...

但如果需要,可使用另一个不同的运算符 –cmatch 进行区分大小写的 regex 比较,如下所示: "Software" –cmatch "soft" 1. 由于在区分大小写比较中,字符串“soft”与“Software”不匹配,所以该表达式返回 False。请注意:尽管 –match 是默认行为,但也可选择使用 –imatch 运算符显式表示不区分大小写。
$initialNum=1; $increment=1; $tmp = Get-Content input.txt | foreach { $n = [regex]::match($_,'id="(\d+)"').groups[1 ].value; if ($n) {$_ -replace "$n", ([int32]$initialNum+$increment); $increment=$increment+1;} else {$_}; } 之后,您可以使用 $tmp > result....

除了语法高亮,一般不用操作。还有两点经常使用的:正则表达式查找替换和列模式编辑。这些可以在VS、Eclipse、Word等里也有,但是有时打开一个文件就慢了。本来想总结记录一下技巧的,却无意中发现已经有人写过了,而且详细的一p。详见这里:3.4. Notepad++的正则表达式替换
