java - 使用Jsoup提取特定的html表格内容

Question

我想从响应式 HTML 表格中提取特定内容，我正在使用 Jsoup。

这是我的表的结构:

<table id="main_widget_table" class="table table-striped table-hover table-condensed table-bordered">
                <tbody>
                <!-- ngRepeat: object in currentView --><tr ng-repeat="object in currentView" class="ng-scope">
                    <td>
                        <a id="main_widget_table_object_name_action" href="#//object/" target="_blank">
                            <b class="ng-binding">TASK_BACKUP</b>

                </tbody>
            </table>

我只有一个来提取粗体标签之间的值，例如第一个 TD 的值为 TASK_TOTO。

这是我的 JAVA 代码:

ublic class HtmlParser {

public class HtmlParser {

public static void main(String[] args) throws Exception {
    Document doc =    Jsoup.connect("http://frstmwarwebsrv2.orsyptst.com:9000/ui/#/en/search?searchString=TSK&filterchecks=nameSWF").get();
    for (Element table : doc.select("#search_results_table")) {
        for (Element row : table.select("tr")) {
            Elements tds = row.select("td");
            System.out.println(tds.get(0).text());   
        }
    }
}

}

我是 JSOUP 的新手，到目前为止我的代码没有显示任何内容。我使用表 ID 来定位表。

谢谢 寻求您的帮助

仅供引用:我的表是使用 Angular JS 生成的，因此 Jsoup 不是提取表数据的最佳方法。

当使用此代码时:

List<WebElement> resultsDiv =    driver.findElements(By.xpath("id('search_results_table')"));
         for (int i=0; i<resultsDiv.size(); i++) {
         System.out.println( resultsDiv.get(i).getText());
         System.out.println (resultsDiv.size());

还是没有显示内容，大小设置为1!!我不知道我做错了什么!!

嗯，根据您提供的 HTML 代码段，该表的 ID 是 main_widget_table，而不是 search_results_table。 (您的代码中的网址无法再访问，因此我无法判断该页面上是否还有其他 search_results_table。)

您可以使用以下命令打印该表中所有 b 标记的文本

for (Element e : doc.select("#main_widget_table b"))
    System.out.println(e.text());
