Question

目前，我可以打印网页的所有网址，但无法打印网址上提供的文字....

例如：

<a class="fbl" href="/preferences?hl=en" jsaction="foot.cst" id="fsettl">Settings</a>

代码只能打印“/ preferences？hl = en”，但不能打印链接文本，即设置....

public static List getLinks(String uriStr) {

List result = new ArrayList<String>();
//create a reader on the html content
try{
    System.out.println("in the getlinks try");
URL url = new URI(uriStr).toURL();
URLConnection conn = url.openConnection();
Reader rd = new InputStreamReader(conn.getInputStream());

// Parse the HTML
EditorKit kit = new HTMLEditorKit();
HTMLDocument doc = (HTMLDocument)kit.createDefaultDocument();
kit.read(rd, doc, 0);

// Find all the A elements in the HTML document
HTMLDocument.Iterator it = doc.getIterator(HTML.Tag.A);
while (it.isValid()) {
    SimpleAttributeSet s = (SimpleAttributeSet)it.getAttributes();

    String link = (String)s.getAttribute(HTML.Attribute.HREF);
    if (link != null) {
            // Add the link to the result list
            System.out.println(link);
        //System.out.println("link print finished");
        result.add(link);
    }
    //System.out.println(link);
    it.next();
}
}

我如何打印网址的内容？
