Android：使用JSoup从HTML检索多个元素

Question

I want to retrieve a title from a div , a start hour and an end hour all of that from a big div called day and inside another div called event

I need to had these items to a list but right now i'am stuck here because it can't retrieve my 3 elements .

Document doc = Jsoup.connect("http://terry.gonguet.com/cal/?g=tp11").get();
Elements days = doc.select("div[class=day]");
Elements event = doc.select("div[class=event]");
for(Element day : days)
{
    System.out.println(" : " + day.text());
    for(Element ev : event)
    {

        Element title = ev.select("div[class=title]").first();
        Element starthour = ev.select("div[class=bub right top]").first();
        Element endhour = ev.select("div[class=bub right bottom]").first();
        System.out.println(title.text()+starthour.text()+endhour.text());

    }
}

Answer 1

None of there is no div in that document which have only day as class argument. They all have day class combined with another class which prevents div[class=day] from finding such div. Same problem applies to div[class=event] selector.

To solve it use CSS query syntax in which . operator is used to describe class attribute
(hint: if you want to select element which has few classes you can use element.class1.class2 ).

So instead of

select("div[class=day]");
select("div[class=event]");

use

select("div.day");
select("div.event");

Also instead of

ev.select("div[class=bub right top]");
ev.select("div[class=bub right bottom]");

you could try using

ev.select("div.bub.right.top");
ev.select("div.bub.right.bottom]");

This will allow you to find div which has all these classes (even if they are not in same order or there are more classes then mentioned in selector).
