Answer 1

Have a look at the documentation.

• http://jsoup.org/cookbook/extracting-data/example-list-links

Here's a working example:

public class StackOverflow20973268 {
    private static String input = "<div class=\"content\">" +
            "<div class=\"label\">Company Name: </div>" +
            "Cartell Chemical Co., Ltd." +
            "<br/>" +
            "<div class=\"label\">Business Owner: </div>" +
            "Michael Chen" +
            "<br/>" +
            "<div class=\"label\">Employees: </div>" +
            "210" +
            "<br/>" +
            "<div class=\"label\">Main markets: </div>" +
            "North America, Europe, China, South Asia" +
            "<br/>" +
            "<div class=\"label\">Business Type: </div>" +
            "Manufacturer" +
            "<br/>" +
            "</div>";

    public static void main(String[] args) throws IOException {
        Document doc = Jsoup.parse(input);
        Elements labels = doc.select("div.content div.label");
        for (Element label : labels) {
            System.out.println(String.format("%s:%s", label.text().trim(),
                    label.nextSibling().outerHtml()));
        }
    }
}

Output:

Company Name::Cartell Chemical Co., Ltd.
Business Owner::Michael Chen
Employees::210
Main markets::North America, Europe, China, South Asia
Business Type::Manufacturer

The Jsoup library is very good for parsing html. It allows extracting values by class/id name or by tree dom traversal. You basically get a div element and find its children which could be text nodes (containing the text to be parsed) or another element which will have its own children. Example you could do something like (not tested with some pseudo)

    doc = Jsoup.parse(info);
        Elements divs= doc.body().getElementsByTag("div");
    for (Element divElement: divs) {
        //extract text of div element with div.textNodes()
        //then 
        //div.nextNode() or something like that 
    }

Basically finding elements and stepping either into them for text or to the next/previous one.
