指定UNI code范围内的动作经常EX pression [英] Specifying a unicode range in an actionscript regular expression

问题描述

我一直在试图写一个普通的前pression，将匹配所有UNI code字字符是这样的：

I have been trying to write a regular expression that would match all unicode word character something like :

/[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF\w]/gi

不过这完全失败，并且不匹配任何东西。我已经尝试了多种前pressions，似乎只要我尝试指定范围的失败。正如有人比我幸运了？

But this completely fails and doesn't match anything. I have tried a variety of expressions and it seems that as soon as I try to specify a range it fails. As anyone been luckier than me?

我希望动作会提供类似\ p {L〕，但如果有任何东西之类的，我无法找到它的文档。

I wish actionscript would offer something like \p{L}, but if there's anything in the like, I couldn't find it in the doc.

推荐答案

您可以使用String.fromChar code与UNI code字符，然后范围将在常规的前pression正常工作。下面是使用你原来的问题的例子：

You can use String.fromCharCode with the unicode characters and then the ranges will work correctly in a regular expression. Here is an example using your original problem:

var exp:RegExp = new RegExp("[" + generateRangeForUnicodeVariables(0x00A0, 0xD7FF) + generateRangeForUnicodeVariables(0xF900, 0xFDCF) + generateRangeForUnicodeVariables(0xFDF0, 0xFFEF) + "\w]", "gi");

private function generateRangeForUnicodeVariables(var1:Object, var2:Object):String
{
   return String.fromCharCode(var1) + "-" + String.fromCharCode(var2);
}
