问Powershell regex Matches[0].Groups与基于Matches.Groups键名的索引EN(是的,我知道,这可能不是最好的方法,但问题发生在构建管道时,这里我只给出了一个被剥离的最小示例,它仍然显示了这种行为。)简介 下载的电视剧经常遇到片头和片尾,有的片头还有广告,比较厌烦,所以笔者就写了个脚本,使用pyt

因此如果你想在源文本中搜索多个出现的模式,你必须切换至RegEx对象,值得一提的是RegEx对象不像-match,Regex对象默认是大小写敏感的,你要想大小写不敏感,可以参考前面的文章。 #-match 只能匹配一个邮箱PSC:\PowerShell>$rawtext="test@pstips.net sent an e-mail that was forwarded to admin@pstips.net."PSC...

要在PowerShell 中使用正则表达式,可以结合相关的命令和操作符。例如,-match操作符用于测试一个字符串是否匹配正则表达式;Select-Stringcmdlet 可在文本中搜索匹配正则表达式的行等。 例如: linux grep grep 指令后跟 “-P" 参数,则表示要使用 “PREs"
-match and -notmatch support regex capture groups. Each time they run on scalar input, and the -match result is True, or the -notmatch result is False, they overwrite the $Matches automatic variable. $Matches is a Hashtable that always has a key named '0', which stores the entire mat...
具有-Regex 选项的 switch 语句 默认情况下,PowerShell 正则表达式不区分大小写。 上面所示的每种方法都有一种不同的方法来强制区分大小写。 对于Select-String,使用CaseSensitive参数。 对于使用正则表达式的运算符,请使用区分大小写的版本:-cmatch、-creplace或-csplit ...
PS C:\PowerShell> ".@ ." -match $parttern False 1. 2. 无论什么时候,希望一个表达式以一个单独的“单词”在文本中出现,可以使用分隔符:单词边界(定位符”\b”),这样正则表达式就会知道你感兴趣的是字符串中除去那些白空格(像空格,制表符,换行符)以外的字符。
ExplicitCapture: Ignores non-named match groups so that only explicit capture groups are returned in the result list. Valid only with RegexMatch. UNARY and BINARY SPLIT OPERATORS The unary split operator (-split <string>) has higher precedence than a comma. As a result, if you submit a comma...
This regex wants four groups of digits with one to three digits each, all of which are separated by a literal period. But consider this example: "300.168.15.20" -match "\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}" (True)
