正则表达式-Unicode属性参考和示例 [英] Regex - Unicode Properties Reference and Examples

问题描述

我对RegexBuddy提供的Regex Unicode属性感到迷失，我无法区分任何Number属性，而Math符号属性似乎只匹配+，但不匹配-，*，/，例如^.

I feel lost with the Regex Unicode Properties presented by RegexBuddy, I cannot distinguish between any of the Number properties and the Math symbol property only seems to match + but not -, *, /, ^ for instance.

在正则表达式Unicode属性上是否有示例文档/参考?

Is there any documentation / reference with examples on regular expressions Unicode properties?

推荐答案

可以在 http://www.unicode.org/Public/UNIDATA/PropList.txt .

每个字符的属性可以在 http://www.unicode.org中找到/Public/UNIDATA/UnicodeData.txt (1.2 MB).

The properties for each character can be found in http://www.unicode.org/Public/UNIDATA/UnicodeData.txt (1.2 MB).

就您而言，

• +(加号)为 Sm ，
• -(HYPHEN-MINUS)是 Pd ，
• *(ASTERISK)为 Po ，
• /(SOLIDUS)也是 Po 和
• ^(环形重音)为 Sk .

• + (PLUS SIGN) is Sm,
• - (HYPHEN-MINUS) is Pd,
• * (ASTERISK) is Po,
• / (SOLIDUS) is also Po, and
• ^ (CIRCUMFLEX ACCENT) is Sk.

最好将它们与[-+*/^]匹配.
