构建正则表达式模式以匹配句子 [英] Constructing regex pattern to match sentence

问题描述

我正在尝试编写一个正则表达式模式，该模式将匹配以多个或一个制表符和/或空格开头的任何句子. 例如，我希望我的正则表达式模式能够匹配你好，我喜欢正则表达式！" 但是我想弄清楚如何在"hello"之后匹配单词.到目前为止，我有这个:

I'm trying to write a regex pattern that will match any sentence that begins with multiple or one tab and/or whitespace. For example, I want my regex pattern to be able to match " hello there I like regex!" but so I'm scratching my head on how to match words after "hello". So far I have this:

    String REGEX = "(?s)(\\p{Blank}+)([a-z][ ])*";
    Pattern PATTERN = Pattern.compile(REGEX);
    Matcher m = PATTERN.matcher("         asdsada  adf adfah.");
    if (m.matches()) {
        System.out.println("hurray!");
    }

任何帮助将不胜感激.谢谢.

Any help would be appreciated. Thanks.

推荐答案

String regex = "^\\s+[A-Za-z,;'\"\\s]+[.?!]$"

^表示开头为"
\\s表示空白
+表示1个或更多
[A-Za-z,;'"\\s]表示任何字母，,，;，'，"或空白字符
$表示结尾为"

^ means "begins with"
\\s means white space
+ means 1 or more
[A-Za-z,;'"\\s] means any letter, ,, ;, ', ", or whitespace character
$ means "ends with"
