Notepad++ 显式量词符号 [英] Notepad++ explicit quantifier notation

问题描述

我一直在使用 Notepad++ 正则表达式引擎，但有一些我无法工作，它是显式量词符号.

I've been playing around with the Notepad++ regular expression engine, but there's something I can't make work, it's the explicit quantifier notation.

我在这里看到了其他一些使用以下语法的帖子:(expr){1,2}

I've seen some other posts here where the following syntax is used : (expr){1,2}

但是，当我在像 k{1,1} 这样简单的测试中使用它时要搜索的文本是 k :没有匹配项.我尝试了很多语法:{1、}、{1} 等.我在这里错过了什么吗?

However, when I use it in a test as simple as k{1,1} where the text to search is k : there is no match. I tried a lot of syntax's : {1,}, {1}, etc. Am I missing something here ?

请原谅我的英语不好，感谢您的回答！

Please excuse my bad english, and thanks for your answers !

推荐答案

从 6.0 版本开始，Notepad++ 支持 PCRE (来源).量词将在这些版本中按预期工作.

Starting with version 6.0, Notepad++ supports PCRE (source). Quantifiers will work as expected in these versions.

Notepad++ 5.9.8 及更低版本的正则表达式引擎不支持量词(来源).

The regex engine of Notepad++ 5.9.8 and lower does not support quantifiers (source).

但是，您可以使用以下量词:

You can, however, use the following quantifiers:

• k*，相当于 k{0,}.
• k+，相当于k{1,}.
• k?，相当于 k{0,1}.

• k*, which is equivalent to k{0,}.
• k+, which is equivalent to k{1,}.
• k?, which is equivalent to k{0,1}.

如果需要其他量词，可以结合上述方法.

If you want other quantifiers, you can combine the above methods.

示例:

• kkk+ 模拟 k{3,}
• kkkk?k? 模拟 k{3,5}

• kkk+ emulates k{3,}
• kkkk?k? emulates k{3,5}
