用正则表达式匹配阿拉伯语文本 [英] Matching arabic text with regex

问题描述

我正在尝试使用正则表达式仅匹配阿拉伯语文本，但出现异常.这是我的代码:

I'm trying to match only arabic text using regex but I'm getting an exception. Here's my code:

txt.matches("\\P{Arabic}+")

例外:

线程主"中的异常java.util.regex.PatternSyntaxException:索引9附近的未知字符属性名称{Arabic} \ P {阿拉伯语} +

Exception in thread "main" java.util.regex.PatternSyntaxException: Unknown character property name {Arabic} near index 9 \P{Arabic}+

推荐答案

使用此字符块

\p{InArabic}+

---

在Java Unicode脚本中，块，类别和二进制属性是用\p和\P(负效果)编写的

---

In java Unicode scripts, blocks, categories and binary properties are written with the \p and \P(negated effect)

使用前缀Is或使用script关键字(

• Scripts are specified either with the prefix Is or by using the script keyword(supported scripts)
• Blocks are specified with the prefix In or by using the keyword block(supported blocks)
• Categories may be specified with the optional prefix Is or using keyword general_category or gc(supported categories)
• Binary properties are specified with the prefix Is (supported properties)
