I only one to extract the value between bold tags, for instance for the first TD the value is TASK_TOTO. 我只有一个提取粗体标记之间的值，例如对于第一个TD，该值是TASK_TOTO。
Here is my JAVA code : 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());
}
}
}
}
I am a newbie to JSOUP and my code does not diplay anything so far. 我是JSOUP的新手，到目前为止，我的代码没有显示任何异常。 I am using the table id to locate the table. 我正在使用表ID来查找表。
Thanks For your help 谢谢你的帮助
FYI : My table is generated using angular JS so Jsoup is not the best way to extract the table data. 仅供参考：我的表是使用有角JS生成的，因此Jsoup并不是提取表数据的最佳方法。
When using this code instead : 当使用此代码代替时：
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());
I still don't get the content displayed and the size is set to 1!! 我仍然没有显示内容，大小设置为1！ I am not sure what I am doing wrong!! 我不确定我在做什么错!!

Well, based on the HTML snippet you provided, the table's id is main_widget_table , not search_results_table . 好吧，根据您提供的HTML代码段，表的ID是main_widget_table ，而不是search_results_table 。 (The URL in your code is no longer accessible, so I can't tell if there's some other search_results_table on that page.) （您代码中的URL不再可用，因此我无法确定该页面上是否还有其他search_results_table 。）
You can print the text of all b tags in that table with 您可以使用以下命令打印该表中所有b标签的文本：
for (Element e : doc.select("#main_widget_table b"))
System.out.println(e.text());
