使用jsoup选择一个非重要的div标签

Question

I'm using jsoup for webscraping and have run into another issue. The div I need information from has no class, id or any special indication. It's buried in the page. Here it is:

<div class="column">
    <div class="form-label">Rate: </div>
    <div>11.082/11.167</div>
    <div class="form-label padding-top">High/Low: </div>  
    <div>1005.0/0.0004</div>
</div>

I need to get the 1st set of numbers but I'm not sure how I can tell jsoup I want them specifically; does anyone have any advice?

Answer 1

1. Select all divs with class="column"
2. Loop through your list of selected elements. Select the first div inside your element that has the text Rate:
3. your Text is inside the 2. div

Sorry Code formatting isnt working o.0

public String getRage(Document document) {
    for(Element e : document.getElementsByClass("column")) {
        if(e.getElementsByTagName("div").get(0).ownText().equals("Rate: ")) {
            return e.getElementsByTagName("div").get(1).ownText();
        }
    }

    return null;
}

Assuming doc is your Document object...

doc.select('.column > div:eq(1)');

should do the job, you basically select the parent div by class, then get all child div's, but filter the child div's so that the element at index 1 is returned (this is a zero based index, so index 1 is the 2nd element)

Personally, i'd switch to jQuery as it uses a far better selector engine, but each to their own...
