Question

我一直在努力从Table获取文本。当我检查firebug时，我可以从xpath获取值，但是当我运行代码时，它不会获取值。该表如下 -

div class="description__table-holder">
<table class="description__table">
<tbody>
<tr>
<td>Test: </td>
<td>9780238905</td>
<td>Pas: </td>
<td>600</td>
</tr>
<tr>
<td>Size: </td>
<td>216 x 274mm</td>
<td>   Result: </td>
<td>  9 To 12  </td>
</tr>
</tbody>
</table>
</div>

我尝试过以下Xpath -

html/body/div[2]/div[5]/div[2]/div/article/section[1]/section[2]/div[4]/div[1]/article/div/table/tbody/tr[1]/td[1]

html/body/div[2]/div[5]/div[2]/div/article/section[1]/section[2]/div[4]//table[@class='description__table']/tbody/tr[1]

html/body/div[2]/div[5]/div[2]/div/article/section[1]/section[2]/div[4]/div[1]/article/div/table/tbody/tr[1]/td/following-sibling::td[3]

但是当我尝试在selenium / c＃/ phantomJS驱动程序中获取值时，我无法.Below是我的代码 -

  var datanew = driver.FindElements(By.XPath("html/body/div[2]/div[5]/div[2]/div/article/section[1]/section[2]/div[4]//table[@class='description__table']/tbody/tr[1]"));

                    var other = "";
                    ArrayList others = new ArrayList();

                    foreach (var dat in datanew)
                    {

                        //var linkDriver = new FirefoxDriver();                                   
                        other = dat.Text;
                        others.Add(other);

                    }

                    string test = driver.FindElement(By.XPath("html/body/div[2]/div[5]/div[2]/div/article/section[1]/section[2]/div[4]/div[1]/article/div/table/tbody/tr[1]/td/following-sibling::td[3]")).Text;

Answer 1

尝试给予一些等待＆amp;检查

Thread.sleep(15);
string test = driver.FindElement(By.XPath("html/body/div[2]/div[5]/div[2]/div/article/section[1]/section[2]/div[4]/div[1]/article/div/table/tbody/tr[1]/td/following-sibling::td[3]")).Text;

如果你没有在你的程序中提供隐式或显式等待，那么有些xpath可能会失败，即使它可能在UI上正常工作。这是因为某些元素在UI上加载需要时间，因此无法找到元素和元素。脚本失败了。另请尝试使用explicit-wait代码，这是更好的方法，我建议您使用relative xpath instead of absolute xpath

虽然可以在DOM中搜索Selenium / C＃Xpath但它不起作用
