selenium webdriver未通过xpath获取的所有src图像亚马逊公司.u

Question

我正在尝试获取产品图像的所有链接&{a1}

但作为回报，我得到的只是图像的一个url链接。在

当我试图查找列表的长度时，甚至没有得到6个webelements（product\u image\u url2）

          product_image_url2 = self.browser.find_elements_by_xpath('//*[@id="main-image- 

               container"]/ul/li/span/span/div/img')

            product_image_url2_count = len(product_image_url2)

             print product_image_url2_count

              image_url2 = []
                for curr_product_image_url2 in product_image_url2:
    image_url2.append(curr_product_image_url2.get_attribute("src"))
                product_dict['image url2']=image_url2

Answer 1

一个css替代方案来匹配这些

#altImages img:not([alt])

#是一个id选择器。img是一个类型选择器（用于标记）。两者之间的space是descendant combinator，这意味着{}是id为altImages元素的子元素。:not([alt])指定子img没有alt属性。[]是属性选择器，:not是CSSpseudo-class。阅读关于他们的here。在

Answer 2

下面是获取左侧img元素的正确xpath。在

//li[@class='a-spacing-small item imageThumbnail a-declarative']//img

以下代码和输出：

^{pr2}$

Answer 3

您的xpath错误。尝试使用xpath。在

from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://www.amazon.co.uk/Autoglym-AG-035001-Interior-Shampoo/dp/B00114WOBC/ref=sr_1_1?ie=UTF8&qid=1553519250&sr=8-1&keywords=715933155337')

product_image_url2 = driver.find_elements_by_xpath('//span[@id="a-autoid-8-announce"]/img')

product_image_url2_count = len(product_image_url2)

print (product_image_url2_count)

image_url2 = []
for curr_product_image_url2 in product_image_url2:
    image_url2.append(curr_product_image_url2.get_attribute("src"))

print(image_url2)

如果你想在字典中存储，请尝试下面的代码。在

^{pr2}$

输出：

6
