JAVA - 如何在selenium中使用xpath

Question

我有这个HTML代码:

<select name="category" id="category">
    <option value="0">&laquo;Seleziona la categoria&raquo;</option>
    <option value='1' style='background-color:#ddd' disabled="disabled" id='cat1' >-- VEICOLI --</option>
    <option value='2'  id='cat2' >Auto</option>
</select>

我必须选择标签标识的WebElement option文本Auto.我尝试了一些解决方案:

d.findElement(By.xpath("/select[@id=category]/option[@id=cat2]")).click();
d.findElement(By.xpath("/select[@id=category]/option[text()='Auto']")).click();
d.findElement(By.xpath("//select[@id=category]/option[Auto]")).click();

但每个人都给了我:

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":"/select[@id=category]/option[@id=cat2]"} ( and other xpath i tried)
Command duration or timeout: 1.52 seconds
For documentation on this error, please visit: http://seleniumhq.org/exceptions/no_such_element.html

什么是正确的语法？有人能帮我吗？

Answer 1

您没有正确的XPath语法.您需要围绕要匹配的文本属性值的引号.尝试:

d.findElement(By.xpath("//select[@id='category']/option[@id='cat2']")).click();
