java - 从字符串中删除所有非单词字符

Question

我想从字符串中删除所有非单词字符，但想保留空格。 示例:

    String a = "Graeme O'Connor Dasha Nicholls  Claire N MacDermott1 • Julia K Catherine Bryant1 Josèô Gil2";
    String b = a.replaceAll("[^\\p{L}]+", " ");
    System.out.println("replaced: " + b);

预期输出:

Graeme O'Connor Claire N MacDermott Julia K Catherine Bryant Josèô Gil

但是我得到了

Graeme O Connor Claire N MacDermott Julia K Catherine Bryant Josèô Gil

Answer 1

替换非单词和非空格和非'字符，然后将多个空格压缩为一个:

String b = a.replaceAll("[^[\\p{L}\\s']]+", "").replaceAll("\\s+", " ");

输出:

replaced: Graeme O'Connor Dasha Nicholls Claire N MacDermott Julia K Catherine Bryant Josèô Gil
