How to parse elements with only one class name included using Jsoup?

Question

For this html:

<div id="list">
    <div class="one two three" date="20130121">
        ...
    </div>
    <div class="one" date="20130122">
        ...
    </div>
    <div class="one two" date="20130123">
        ...
    </div>
    <div class="one" date="20130124">
        ...
    </div>
</div>

I would like to extract the date element with class = "one" only, so that if class is included "one" but having other class is not correct.
My expect answer should be date="20130122" and date="20130124"

I tried to use:

Element outestDiv = doc.getElementById("list");
Elements eachDayBox = outestDiv.select("div.one");

But eachDayBox.size() return 4 but not 2. So how to extract with class only "one"?? Also, how to get element in "date"??

Answer 1

Use [attribute=value] in select

Elements eachDayBox = outestDiv.select("div[class=one]"); //class only equal to one

Reference

Answer 2

This will work.

Elements elements = doc.getElementsByAttributeValue("class", "one");
for(int i=0;i<elements.size();i++){
    Element tmp=elements.get(i);
    System.out.println(tmp.attr("date"));
}

Answer 3

获取日期值

String date = eachDayBox .attr("date");
