无法弄清楚如何抓取特定文本 - 使用 Jsoup

Question

我刚开始学习如何使用 JSoup。我想我已经成功地选择了 html 的这一部分，并且我通过执行 .select("span.title").text 成功地取出了“DARK SOULS III Deluxe Edition”，但在这种情况下我试图获取价格84.98 美元和 55.23 美元。我尝试做 .select("div.col search_price responsive_secondrow").text 但它显示为空白。我想知道是否有人可以帮助我弄清楚如何提取该部分，在此先感谢！这是页面部分的html。

完整的html是view-source:http://store.steampowered.com/search/?filter=topsellers

<a href="http://store.steampowered.com/sub/94174/?snr=1_7_7_topsellers_150_1"  data-ds-packageid="94174" data-ds-appid="374320,442010"onmouseover="GameHover( this, event, 'global_hover', {&quot;type&quot;:&quot;sub&quot;,&quot;id&quot;:94174,&quot;public&quot;:1,&quot;v6&quot;:1} );" onmouseout="HideGameHover( this, event, 'global_hover' )" class="search_result_row ds_collapse_flag" >

                        <div class="col search_price discounted responsive_secondrow">

                <div style="clear: left;"></div>
            </a>

Answer 1

使用 doc.select("a.search_result_row") 代替：

public class JsoupSteamTest {

    public static void main(String[] args) throws IOException {

        Document doc = Jsoup.connect("http://store.steampowered.com/search/?filter=topsellers").userAgent("Mozilla")
                .get();

        Elements table = doc.select("a.search_result_row");

        Iterator<Element> ite = table.iterator();
        while (ite.hasNext()) {
            Element element = ite.next();
            System.out.println(element.text());

        }
    }
}

你会得到一个这样的列表：

PLAYERUNKNOWN'S BATTLEGROUNDS 23 Mar, 2017 29,99€
Steel Division: Normandy 44 Coming Soon 39,99€
DARK SOULS™ III 11 Apr, 2016 -50% 59,99€ 29,99€

您的特殊问题来自具有多个类的 div。

要选择具有多个类的元素，请在选择中使用点而不是空格：

doc.select("div.col.search_price.discounted.responsive_secondrow");
