如果你有一個(gè)包含HTML的字符串，你可以像這樣使用Jsoup庫(kù)來獲取HTML元素:

String htmlTable= "<table><tr><td>Hello World!</td></tr></table>";
Document doc = Jsoup.parse(htmlTable);

// then use something like this to get your element:
Elements tds = doc.getElementsByTag("td");

// tds will contain this one element: <td>Hello World!</td>

我在某個(gè)地方發(fā)現(xiàn)了這個(gè)(不記得在哪里了):

public static DocumentFragment parseXml(Document doc, String fragment)
 {
    // Wrap the fragment in an arbitrary element.
    fragment = "<fragment>"+fragment+"</fragment>";
    try
    {
        // Create a DOM builder and parse the fragment.
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        Document d = factory.newDocumentBuilder().parse(
                new InputSource(new StringReader(fragment)));

        // Import the nodes of the new document into doc so that they
        // will be compatible with doc.
        Node node = doc.importNode(d.getDocumentElement(), true);

        // Create the document fragment node to hold the new nodes.
        DocumentFragment docfrag = doc.createDocumentFragment();

        // Move the nodes into the fragment.
        while (node.hasChildNodes())
        {
            docfrag.appendChild(node.removeChild(node.getFirstChild()));
        }
        // Return the fragment.
        return docfrag;
    }
    catch (SAXException e)
    {
        // A parsing error occurred; the XML input is not valid.
    }
    catch (ParserConfigurationException e)
    {
    }
    catch (IOException e)
    {
    }
    return null;
}
