我如何使用Selenium WebDriver获得HTML中的文本？

Question

html prettyprint-override"><div class="highcharts-tooltip" style="position: absolute; left: 83px; top: 15px; visibility: hidden;">
  <span id="ext-gen1350" style="position: absolute; white-space: nowrap; font-family: " Lucida Grande ","Lucida Sans Unicode
  ",Verdana,Arial,Helvetica,sans-serif; font-size: 12px; color: rgb(51, 51, 51); margin-left: 0px; margin-top: 0px; left: 8px; top: 8px;" zindex="1">
<span style="color:#000000">Index</span>
  <br/>
  <b>< 600</b>
  1532.6788418669355
  </span>
</div>

var options = Driver.FindElements(By.XPath("//div[@class='highcharts-tooltip']//following::span"));

var x = Driver.FindElement(By.CssSelector(".highcharts-tooltip")).GetAttribute("textContent");

//var y = Driver.FindElement(By.XPath("//*[@class='highcharts-tooltip']//b")).GetAttribute("textContent");

var z = Driver.FindElement(By.XPath("//*[@class='highcharts-tooltip']//span")).GetAttribute("textContent");

z = Driver.FindElement(By.XPath("//*[@class='highcharts-tooltip']/span")).GetAttribute("textContent");

z = Driver.FindElement(By.XPath("//*[@class='highcharts-tooltip']/span")).GetAttribute("text");

**var a = Driver.FindElement(By.XPath("//*[@class='highcharts-tooltip']/span/text()"));** this xpath works in Firebug perfectly, but not using Webdriver...

//var b = Driver.FindElements(By.XPath("//*[@class='highcharts-tooltip']/span/text()"));

Answer 1

因为您试图访问的WebElement是隐藏的，所以getText()方法返回一个空字符串。

此外，您试图检索的文本没有ID或标记，因此我们必须检索父文本。

Driver.FindElement(By.CssSelector(".highcharts-tooltip")).GetAttribute("textContent");

会给你，
