JAVA-如何在硒中使用xpath [英] JAVA - How to use xpath in selenium

问题描述

我有这个html代码:

i have this html code:

<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>

，我必须选择由标签option和文本Auto标识的WebElement. 我尝试一些解决方案，例如:

and i have to select the WebElement identified by the tag option with text Auto. I try some solution like:

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();

但是每个人都给我

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?有人可以帮我吗?

what is the right syntax? can someone help me?

推荐答案

您的XPath语法不正确.您需要在要匹配的文本属性值周围加上引号.试试:

You don't have your XPath syntax right. You need quotes round the text attribute values you're matching against. Try:

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