使用Java标准库将HTML字符转换回文本 [英] Convert HTML Character Back to Text Using Java Standard Library

问题描述

我想用Java Standard Library将一些HTML字符转换回文本。我想知道是否有任何库会达到我的目的吗？

I would like to convert some HTML characters back to text using Java Standard Library. I was wondering whether any library would achieve my purpose?

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    // TODO code application logic here

    // "Happy & Sad" in HTML form.
    String s = "Happy & Sad";
    System.out.println(s);

    try {
        // Change to "Happy & Sad". DOESN'T WORK!
        s = java.net.URLDecoder.decode(s, "UTF-8");
        System.out.println(s);
    } catch (UnsupportedEncodingException ex) {

    }
}

推荐答案

我认为雅加达共享Lang图书馆的StringEscapeUtils.escapeHtml（）和unescapeHtml（）方法是你正在寻找的。请参阅 http：// commons.apache.org/proper/commons-lang/javadocs/api-3.1/org/apache/commons/lang3/StringEscapeUtils.html 。

I think the Jakarta Commons Lang library's StringEscapeUtils.escapeHtml() and unescapeHtml() methods are what you are looking for. See http://commons.apache.org/proper/commons-lang/javadocs/api-3.1/org/apache/commons/lang3/StringEscapeUtils.html .
