[英]Javascript regular expression for punctuation (international)?
I need a regular expression to match against all punctuation marks, such as the standard [,!@#$%^&*()], but including international marks like the upside-down Spanish question mark, Chinese periods, etc. My google-fu is coming up short.我需要一个正则表达式来匹配所有标点符号,例如标准的 [,!@#$%^&*()],但包括国际标记,如倒置的西班牙问号、中文句号等。我的谷歌-fu 快不行了。 Does anyone have such a regular expression on hand that's compatible with Javascript?
有没有人手头有这样一个与 Javascript 兼容的正则表达式?
Adding to @stema's answer ( https://stackoverflow.com/a/7578937/114140 )... here is the regex as a string (so you don't need to bloat your project with XRegExp).添加到@stema 的答案( https://stackoverflow.com/a/7578937/114140 )...这里是作为字符串的正则表达式(因此您无需使用 XRegExp 使您的项目膨胀)。

If it's possible for you to use a plugin, there is a plugin for JavaScript: XRegExp Unicode plugins .如果您可以使用插件,那么有一个 JavaScript 插件: XRegExp Unicode plugins 。 That adds support for Unicode categories, scripts, and blocks (I personally have only read about it, I never used it).
这增加了对 Unicode 类别、脚本和块的支持(我个人只读过它,我从未使用过它)。
With this plugin it should be possible to use Unicode categories like \\p{P}
as explained at regular-expressions.info .使用此插件,应该可以使用 Unicode 类别,如正则表达式.info 中所述的
\\p{P}
。
Update: OK, I tested it, and it seems to work fine.更新:好的,我测试了它,它似乎工作正常。
You need to get the lib from XRegExp and additionally the Unicode Base and Unicode Category plugins (linked above).您需要从XRegExp获取 lib 以及另外的 Unicode Base 和 Unicode Category 插件(链接在上面)。
<script src="xregexp.js"></script>
<script src="addons/unicode-base.js"></script>
<script src="addons/unicode-categories.js"></script>
<script>
var unicodePunctuation = XRegExp("^\\p{P}+$");
alert(unicodePunctuation.test("?.,;!¡¿。、·")); // true
</script>
The above alerts true
.以上警告为
true
。 I included some Spanish and Chinese punctuation in my test string, "?.,;!¡¿。、·"
.我在测试字符串中包含了一些西班牙语和中文标点符号,
"?.,;!¡¿。、·"
。
嗯......不知道它会有多广泛,但你可以使用这个:
[^\w\s\n\t]
Your regex would look something like...你的正则表达式看起来像......
/[,!@#$%^&*()\u9999]/
Where you replace each \香
with the Unicode codepoint for the other punctuation characters.您将每个
\香
替换为其他标点字符的 Unicode 代码点。
If you could find a bunch in a range , you could specify that with the -
range operand, eg \馐-\香
.如果你能找到的范围内的一堆,你可以指定与
-
范围内操作,如\馐-\香
。
As far as I know you can't use something like \\pP
in JavaScript regexes.据我所知,你不能在 JavaScript 正则表达式中使用类似
\\pP
东西。
For Python this regex to remove from the start and end any type of punctuation marks:对于 Python,此正则表达式从开头和结尾删除任何类型的标点符号:
import re
def cleanspecialcharacters(str):
regex = re.compile((
'^[/\"_\(\)&*\$¥\^\+=`~<>\{\}\[\]\|\-!#%\,\:;@¡§«¶·»¿;·՚-՟։֊؉،॥॰෴๏๚๛༄-༒༔༺-༽྅჻፠-፨᐀᙭᙮។-៖៘-៚‧‰-⁃⁅-⁑⁓-⁞⁽⁾₍₎、〃〈-【】〔-〟〰〽゠・﴾﴿︐-︙︰-﹒﹔-﹡﹣﹨﹪﹫!-#%-*,-/:;?@[-]_{}⦅-・〔〕《》]*|'
'([/\"_\(\)&*\$¥\^\+=`~<>\{\}\[\]\|\-!#%\,\:;@¡§«¶·»¿;·՚-՟։֊؉،॥॰෴๏๚๛༄-༒༔༺-༽྅჻፠-፨᐀᙭᙮។-៖៘-៚‧‰-⁃⁅-⁑⁓-⁞⁽⁾₍₎、〃〈-【】〔-〟〰〽゠・﴾﴿︐-︙︰-﹒﹔-﹡﹣﹨﹪﹫!-#%-*,-/:;?@[-]_{}⦅-・〔〕《》])*$'))
str = regex.sub('', str)
return str
From ES 2018, Unicode property escapes are supported.从 ES 2018 开始,支持Unicode 属性转义。 You can use
\\p{Punctuation}
or just \\p{P}
(the same as the XRegExp answer) to match any punctuation character (by the Unicode definition), or \\P{Punctuation}
to match any non-punctuation character.您可以使用
\\p{Punctuation}
或仅使用\\p{P}
(与 XRegExp 答案相同)来匹配任何标点字符(根据 Unicode 定义),或使用\\P{Punctuation}
来匹配任何非标点字符。
If you want to match any "non-word" character, like a Unicode version of \\W
, you can try something like:如果您想匹配任何“非单词”字符,例如
\\W
的 Unicode 版本,您可以尝试以下操作:
[^\p{Alphabetic}\p{Mark}\p{Decimal_Number}\p{Connector_Punctuation}\p{Join_Control}]
(as recommended in the proposal for the feature). (如该功能的提案中所建议的那样)。 You might want to remove
\\p{Connector_Punctuation}
, since that includes underscores and similar.您可能想要删除
\\p{Connector_Punctuation}
,因为它包含下划线和类似内容。
Don't forget to add the u
flag to your regular expression to make it Unicode-aware and enable this feature.不要忘记将
u
标志添加到您的正则表达式以使其能够识别 Unicode 并启用此功能。
