Question

我正在尝试从以下链接中提取一些数据，我可以检索该页面的任何元素的内容，但保留动态时间的内容除外。我尝试了所有可能的CSS选择器，但没有一个工作。您可能想要检查元素of this page。

HTML：

    <div class="meta">
        <span class="information-row properties"></span>
        <span class="information-row">
            <span class="date" data-time="1414176068">

                Today 12:41 am <!-- This is the text I want to extract -->

            </span>

            ,


            <span class="category"></span>

            ,


            <span class="location"></span>
        </span>
    </div>

Java代码：

import java.io.IOException;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

public class Main {

    /**
     * @param args
     */
    public static void main(String[] args) throws IOException {

            Document doc=Jsoup.connect("http://bikroy.com/en/ads-in-bangladesh?query=Nokia&category=&location=").userAgent("Chrome").timeout(999999).get();

            Elements titles = doc.select("div.title");
            Elements prices = doc.select("span.data");
            Elements locations = doc.select("span.location");
            Elements dates = doc.select("span.date");
            //Elements dates = doc.select("[data-time*=14]");

            for(int i = 0; i < titles.size(); i++) {
                  System.out.println("\nTitle: " + titles.get(i).text() + "\nPrice: " +  prices.get(i).text() + "\nLocation: " +  locations.get(i).text() + "\nDate: " +  dates.get(i).text());
            }


   }
}

Answer 1

如果你查看页面的原始html，span class="date"没有内容，页面必须选择data-time属性并使用javascript进行转换。

我认为你必须这样做。读取数据时间并转换为日期。

提示：日期时间看起来是以秒为单位的时间戳。

Jsoup：无法检索时间/日期元素
