从字符串中删除 HTML 标记

Is there a good way to remove HTML from a Java string? A simple regex like

replaceAll("\<.*?>", "") 

will work, but things like & wont be converted correctly and non-HTML between the two angle brackets will be removed (i.e. the .*? in the regex will disappear).

解决方案

Use a HTML parser instead of regex. This is dead simple with Jsoup.

public static String html2text(String html) {
    return Jsoup.parse(html).text();
}

Jsoup also supports removing HTML tags against a customizable whitelist, which is very useful if you want to allow only e.g. <b>, <i> and <u>.
