如何從包含撇號的下拉列表中選擇答案？

Question

當我嘗試使用webdriver選擇帶撇號的回答（發生在所有瀏覽器中）時，我得到了這個InvalidSelectorException。我試圖用反斜槓逃脫撇號，但我認爲這是因爲它存儲在它沒有得到逃脫的變量：

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) 
Command duration or timeout: 219 milliseconds

這裏是Java代碼。變量quesiton和答案是字符串列表從DB：

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

下面是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> 

有沒有一種方式來逃避被存儲在一個變量或另一個字符串的撇號繞過這個方法還是撇號甚至是問題？任何幫助將非常感激。謝謝！

試試這個：

<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> 

選項標記之間，因爲它們沒有貼不應該是必要的，但以防萬一。

我希望這個工程
