    Here, I need to get the option value pair in an array.While testing the code out i executed the following code:

     String q=doc.select("eight columns").text();
     System.out.println(q); 

使用JSoup选择器语法，我应该把整个代码放入字符串q中。但我得到一个空值，而不是（logcat）。如何？

也doc.select（"h3. r

我介绍了DOM概念，如父概念、同级概念。在那里我阅读了关于节点的概念。因此，在编写元素e=doc时。。。。或元素e=doc

我们可以用创建节点来代替吗？建议这样做可行吗？

我几乎无法从html中查看字符串中的值。

如果你想获得类八列，你可以使用getElementsByClass（）示例：

Elements eightcolumns = doc.getElementsByClass("eight columns");
            String str = eightcolumns.first().text();

或选择（）

 Elements eightcolumns = doc.select("div.eight columns");
            String str = eightcolumns.first().text();
