为什么getElementsByClass在jsoup中不起作用？

Question

I am trying to get some elements by their class names. Here is the HTML file:

<div id="container">
    <div id="page_clips">
        <div id="content" class="margin-right-5">
            <div class="product-grid margin-left-5">
                <div>.....</div>
                <div>.....</div>
                <div>.....</div>
             </div>
        </div>
    </div>
</div>

Here, what i want to get is, the div that has the class="product-grid margin-left-5". Here is what i do:

Document doc = Jsoup.connect(link).get();
Element page_clips = doc.getElementById("page_clips");
Element page_clip_content = page_clips.getElementById("content");

This piece of code succesfully gets the div with the id "content". Then when i try,

Elements elementsIWantToGet= page_clip_content.getElementsByClass("product-grid margin-left-5");

it returns empty. What am i doing wrong? Isn't the name of the class attribute of that div is "product-grid margin-left-5" ? Can anyone help?

Thanks

Because getElementsByClass doesn't support multiple class names. By giving it "product-grid margin-left-5" , do you mean to find all elements with both classes? Or either class?

Either way, use select , which accepts CSS selectors:

For elements with both :

.. = page_clip_content.select(".product-grid.margin-left-5");

For elements with either :

.. = page_clip_content.select(".product-grid, .margin-left-5");
