I would like to unescape a XML character entity reference ü to ü in Java.
How can I achieve this?

推荐答案

可能您需要一个额外的库来将该代码转换为Unicode字符，例如 StringEscapeUtils .

Probably you need an additional library to convert that codes to Unicode chars, like Apache Commons Lang. This library has the class StringEscapeUtils.

import org.apache.commons.lang3.StringEscapeUtils;

public class Unescape {
    public static void main(String[] args) {
        String str = StringEscapeUtils.unescapeHtml4("ü");
        System.out.println(str);
    }
}

输出:

ü
