假设要解析字符串而不是HTML文档(根据您的问题)，此方法将起作用:

Assuming String rather than HTML documents are being parsed (as per your question) this method will work:

public String escapeHtml(String source) {
    Document doc = Jsoup.parseBodyFragment(source);
    Elements elements = doc.select("b");
    for (Element element : elements) {
        element.replaceWith(new TextNode(element.toString(),""));
    }
    return Jsoup.clean(doc.body().toString(), new Whitelist().addTags("a").addAttributes("a", "href", "name", "rel", "target"));
}

您可以将"b"标签设为自变量，以传递要转义的标签列表.

You could make the "b" tag an argument to pass in a list of tags you wish to escape.

关联的通过JUnit测试:

The associated passing JUnit test:

@Test
public void testHtmlEscaping() throws Exception {
    String source = "This is <b>REALLY</b> dirty code from <a href=\"www.rubbish.url.zzzz\">haxors-r-us</a>";
    String expected = "This is &lt;b&gt;REALLY&lt;/b&gt; dirty code from \n<a href=\"www.rubbish.url.zzzz\">haxors-r-us</a>";
    String transformed = transformer.escapeHtml(source);
    assertEquals(transformed, expected);
}

请注意，由于JSoup格式化了页面，因此我在测试的预期"字符串中的"a"标记之前添加了行返回"\ n".

Note that I added a line return "\n" before your "a" tag in my test's "expected" String because JSoup formats the page.
