只允许字母和"专用"字母(EEA等),通过一个正则表达式 [英] Allow only letters and "special" letters (éèà etc.) through a regex
问题描述
我想匹配的字符串,看它是否只包含了字母。各类信件应该被允许。因此,典型的 A-ZA-Z
,也áàéèó...
等。
I am trying to match a string to see if it only consists out of letters. All kinds of letters should be allowed. So the typical a-zA-Z
, but also áàéèó...
etc.
我试着用下面的正则表达式匹配它:([\S])*
I tried to match it with the following regex: ([\S])*
但是,这也让像 \ /<字符;> *()...
等,这些都是很明显的不一个名字属于字符。如何在正则表达式的样子时,我只希望允许字母和特别的信吗?
But this also allows characters like \/<>*()...
etc. Those are obviously characters that don't belong in a name. How does the regex looks like when i only want to allow letters and 'special' letters?
推荐答案
您可以使用字符类,说正是:
You can use the character class that says exactly that:
\p{L}
所以,正则表达式
^\p{L}+$
将如果字符串只包含字母相匹配。如果你期望组合字符,然后
will match if the string consists only of letters. If you expect combining characters, then
^(\p{L}\p{M}*)+$
工作
快速PowerShell的测试:
Quick PowerShell test:
PS> 'foo','bär','a.b','&^#&%','123','кошка' -match '^\p{L}+$'
foo
bär
кошка
