使用 Xpath 提取文本

Question

我正在尝试使用 Selenium C# 提取元素后的文本。

我已经找到了 XPath，用于使用 XPath Checker 定位文本。

//*[@id='selectedEciId_5555555']/../following-sibling::text()[1]

在 XPath Checker 中使用上述返回：“5555555 (Customer 5 Name)”。

我已尝试使用以下代码将文本“5555555（客户 5 名称）”提取到使用以下代码行的变量中。

var customer = driver.FindElement(By.XPath("//*@id='selectedEciId_2217611']/../following-sibling::text()[1]")).Text;

但收到一条错误消息，指出“Window.getComputedStyle 的参数 1 未实现接口元素。”

有人可以帮助使用正确的代码来提取文本吗？

Answer 1

我相信当 Selenium 在获取文本之前尝试检查元素的可见性时会发生错误。

一种解决方案是使用 javascript 获取文本

var script = @"return arguments[0].nodeValue;";

var element = driver.FindElement(By.XPath("//*@id='selectedEciId_1111111']/../following-sibling::text()[1]"));

IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
elementText = js.ExecuteScript(script, element).ToString();
