如何根据使用 Selenium 的 html 从使用 xpath 找到的元素中检索属性 aria-label 的值 [英] How to retrieve the value of the attribute aria-label from element found using xpath as per the html using Selenium

问题描述

我有以下 HTML 跨度:

I have the following HTML span:

<button class="coreSpriteHeartOpen oF4XW dCJp8">
    <span class="glyphsSpriteHeart__filled__24__red_5 u-__7" aria-label="Unlike"></span>
</button>

我还有一个 webElement 表示包含我使用 xpath 找到的这个跨度的按钮.如何从元素中检索 aria-label 值(不同)?

I also have a webElement representing the button containing this span that I have found using xpath. How can I retrieve the aria-label value (Unlike) from the element?

我尝试这样做:

btn = drive.find_element(By.xpath, "xpath") 
btn.get_attribute("aria-label")

但它什么都不返回.如何检索元素的文本值带有来自元素对象的aria-label"属性?

but it returns nothing. How to retrieve the text value of an element with 'aria-label' attribute from the element object?

推荐答案

aria-label 是 span 元素的属性，而不是按钮.你可以这样得到:

aria-label is attribute of span element, not button. You can get it like this:

btn = drive.find_element(By.xpath, "xpath") 
aria_label = btn.find_element_by_css_selector('span').get_attribute("aria-label")

或者，如果您的目标是找到包含属性 aria-label="Unlike" 的 span 按钮:

Or if your goal is to find button with span contains attribute aria-label="Unlike":

btn = drive.find_element(By.XPATH, '//button[./span[@aria-label="Unlike"]]')
#you can add class to xpath also if you need
btn = drive.find_element(By.XPATH, '//button[./span[@aria-label="Unlike"] and contains(@class,"coreSpriteHeartOpen)]')
