java - Java jsoup-清除链接以外的所有标签

输入字符串:
<b>Test link</b> <a href="https://www.w3schools.com">Visit W3Schools</a>
预期结果:
Test link <a href="https://www.w3schools.com">Visit W3Schools</a>
我对jsoup的尝试:

public String cleanHtml(String html)
    {
        Whitelist whitelist = Whitelist.none();
        whitelist.addTags("a");

        return Jsoup.clean(html, whitelist);
    }

结果是:
Test link <a>Visit W3Schools</a>
如何删除所有标签，但保留整个a href？

最佳答案

您需要使用addAttributes。在这里，您传递允许的属性列表whitelist.addAttributes("a","href","id","more")；

试试这个:

String html = "<b>Test link</b> <a href=\"https://www.w3schools.com\">Visit W3Schools</a>";
    Whitelist whitelist = Whitelist.none();
    whitelist.addTags("a");
    whitelist.addAttributes("a","href");

    System.out.println(Jsoup.clean(html, whitelist));
