Question

以下是我的代码，用于解析HTML并将<small>标记的出现替换为<span>的

String html =
        "<html>"+
        "<body bgcolor=''>"+
                "<table class='tabletext'>" +
                "<tr align='center' style='background:#FFFFFF'>" +
                "<td class='classa'><span id='fd'><span>10</span></span></td>" +
                "<td>10.00</td>" +
                "<td><small>&pound;0.00</small></td>" +
                "<td>&pound;280.00</td>" +
                "<td>" +
                "<ul>"+
                "<li><a href=''>ok</a></li>"+
                "</ul>"+
                "<a href='/cart.php?action=add&qty=10&id=2628' title='Click here to add this item to your cart'>" +
                "<img alt='Click here to add this item to your cart' src='/images/addtocart.gif' border='0' />" +
                "</a>" +
                "</td>" +
                "</tr>" +
                "<tr><td><span>Hello2</span></td></tr>"+
                "</table>"+
                "</body>"+
                "</html>";
        Document doc = Jsoup.parse(html);


        Elements elements = doc.select("small");


        Element element2 = elements.get(0);
        System.out.println(element2.replaceWith("<span>"));

但是上面的代码工作不正常。

Answer 1

如果您要将所有<small>代码替换为<span>，则应正确使用Node.replaceWith。

Document doc = Jsoup.parse(html);
for (Element small: doc.select("small")) {
  small.replaceWith(new Element(Tag.valueOf("span"), "").text(small.text()));
}
System.out.println(doc.html()); // prints html with <small> replaced by <span>

Answer 2

另一种解决方案是重命名标记：

Document doc = Jsoup.parse(html);
doc.select("small").tagName("span");

Answer 3

它适用于所有标签：

Document html=Jsoup.parse(htmlString);
html.select("small").tagName("span");

我正在寻找一个HTML解析器，可以用“span”替换“小”标签
