如何使用具有多個類名元素的Jsoup解析html文件？

Question

下面的Java代碼適用於具有css-sched-table-title之類的html文件。

但是我有多個類名稱可以在html文件中找到，例如css-sched-waypoints，css-sched-times。 如何在jsoup中使用getElementsByClass方法組合搜索。 我不想多次編寫代碼，因為我想保留訂單。 我的意思是我想要類似

doc.getElementsByClass（“ css-sched-table-title” || doc.getElementsByClass（“ css-sched-waypoints”）;

    Document doc = Jsoup.parse(content);

    Elements ele = doc.getElementsByClass("css-sched-table-title");
    for (Element link : ele) {

       String linkText = link.text();
       System.out.println(linkText);    

   }

。

<tr ALIGN="CENTER">
           <td CLASS="css-sched-times">&nbsp;</td>
           <td CLASS="css-sched-times">6:15</td>
           <td CLASS="css-sched-times">&nbsp;</td>

從您先前的查詢中獲得線索，當我嘗試通過有效的Selector語法將3個td組合在一起時，我得到了您期望的結果。

doc.select("td[class=css-sched-table-title], td[class=css-sched-waypoints], td[class=css-sched-times]")

請注意 ，您可以在選擇器語法中組合多個條件，例如： Elements row = doc.select("td[class=css-sched-table-title], td[class=css-sched-waypoints], td[class=css-sched-times]"); 有效地成為您的OR運算符。

Elements row = doc.select("td[class=css-sched-table-title], td[class=css-sched-waypoints], td[class=css-sched-times]");
        System.out.println("::Total Count::" + row.size());

        Iterator<Element> iterator = row.listIterator();
        while (iterator.hasNext()) {
            Element element = iterator.next();
            String id = element.attr("id");
            String classes = element.attr("class");
            String value = element.text();
            System.out.println("Id : " + id + ", classes : " + classes
                    + ", value : " + value);
        }

給人，
