Question

当我尝试使用webdriver在其中选择带撇号的答案时，我得到了这个InvalidSelectorException（在所有浏览器中都会发生）。我试图使用反斜杠来逃避撇号，但我认为这是因为它存储在一个变量中，它没有被转义：

org.openqa.selenium.InvalidSelectorException: The xpath expression '//select[@name='titleCode']/option[@value='I'm in college']' cannot be evaluated or does notresult in a WebElement (WARNING: The server did not provide any stacktrace information)

这是java代码。变量quesiton和answer是来自DB的字符串列表：

driver.findElement(By.xpath("//select[@name='" + question + "']/option[@value='" + answer + "']")).click();

这是HTML：

<select id="select1" class="select" name="titleCode">
<option selected="" value="">Please select...</option>
<option value="I'm in high school">I'm in high school</option>
<option value="I'm in college">I'm in college</option>
</select>

有没有办法逃避存储在变量或其他方式的字符串的撇号，或者是撇号甚至问题？任何帮助都会非常感激。谢谢！

尝试一下：

    <select id="select1" class="select" name="titleCode">
    <option selected="" value="">Please select...</option>
    <option value="I&#39;m in high school">I&#39;m in high school</option>
    <option value="I&#39;m in college">I&#39;m in college</option>
</select>

选项标签之间不应该是必需的，因为它们没有发布，只是以防万一。

我希望这有效
