Question

我想从字符串中删除所有非单词字符，但想要保留空格。例如：

预期产出：

Graeme O'Connor Claire N MacDermott Julia K CatherineBryantJosèôGil

但我得到了

Graeme O Connor Claire N MacDermott Julia K CatherineBryantJosèôGil

Answer 1

替换非单词和非空格以及非'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

Answer 2

尝试这样的事情：

    String a = "Graeme O'Connor Dasha Nicholls  Claire N MacDermott1 • Julia K Catherine Bryant1 Josèô Gil2";
    String b = a.replaceAll(".*?(\\b[\\p{L}']+)[^\\p{L}']*", "$1 ");
    System.out.println("replaced: " + b);

打印：

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