【问题描述】：

html_entity_decode($string, ENT_QUOTES, 'UTF-8'); 的 Java 等价物是什么？在 PHP 中。示例：

这是我的文字，

Mivan is an aluminium formwork system developed by a European construction company. In 1990, the Mivan Company Ltd. from Malaysia started manufacturing these formwork systems. Today, more than 30,000sqm of formwork from Mivan Co. Ltd. 

Advantages:

· More seismic resistance

· Increased durability

· Lesser number of joints and reduced leakages

· Higher carpet area

要求的格式是：

Mivan is an aluminium formwork system developed by a European construction company. In 1990, the Mivan Company Ltd. from Malaysia started manufacturing these formwork systems. Today, more than 30,000sqm of formwork from Mivan Co. Ltd. Advantages: · More seismic resistance · Increased durability · Lesser number of joints and reduced leakages .Higher carpet area.

在java中使用以下正则表达式删除空格/制表符/换行不起作用

comment=comment.replaceAll("\\s+", "");
comment=comment.replaceAll("\t\n\r", "");

【问题讨论】：

这与 HTML 实体有什么关系？代码中是否包含任何 html 实体？
这不是您在示例中提供的文本。您能否编辑您的问题并编写您遇到问题的实际文本、您真正期望的结果、您正在使用的代码以及该代码产生的您不喜欢的结果？顺便说一句，相关的PHP命令不是strip_tags而不是html_entity_decode吗？

只需用一个空格替换一个或多个换行符。

String s ="Mivan is an aluminium formwork system developed by a European construction company. In 1990, the Mivan Company Ltd. from Malaysia started manufacturing these formwork systems. Today, more than 30,000sqm of formwork from Mivan Co. Ltd. \n" + 
            "\n" + 
            "Advantages:\n" + 
            "\n" + 
            "· More seismic resistance\n" + 
            "\n" + 
            "· Increased durability\n" + 
            "\n" + 
            "· Lesser number of joints and reduced leakages\n" + 
            "\n" + 
            "· Higher carpet area";
String comment = s.replaceAll("[\\n\\r]+", " ");
System.out.println(comment);

输出：

Mivan is an aluminium formwork system developed by a European construction company. In 1990, the Mivan Company Ltd. from Malaysia started manufacturing these formwork systems. Today, more than 30,000sqm of formwork from Mivan Co. Ltd.  Advantages: · More seismic resistance · Increased durability · Lesser number of joints and reduced leakages · Higher carpet area
