java使用Jsoup提取特定的html表内容
我想从响应的HTML表中提取单独的内容，我使用的是Jsoup
以下是我的表格结构：
<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">

我只需要提取粗体标记之间的值，例如，对于第一个TD，值为TASK_TOTO
以下是我的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。我正在使用表id查找表
谢谢 谢谢你的帮助
仅供参考：我的表格是使用angular JS生成的，因此Jsoup不是提取表格数据的最佳方式
改用此代码时：
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());
我仍然无法显示内容，大小设置为1！！我不确定我做错了什么
# 1 楼答案
根据您提供的HTML代码片段，表的id是
main_widget_table，而不是search_results_table。（代码中的URL不再可访问，因此我无法判断该页面上是否有其他search_results_table。）您可以使用
