html.xpath
使用这种 xpath 查询方式的前提是要先通过 webdriver 拿到页面的字符串类型的 html 源代码，然后使用 lxml.tree() 方法将源代码转成可通过 DOM 树的形式进行层级遍历。代码如下：

from lxml import etree
text = driver.page_source
html = etree.HTML(text)
review_ids = html.xpath('//*[@class="a-section review aok-relative"]/@id')
print(review_ids)
if review_ids:
for review_id in review_ids:
print(review_id)
driver.xpath
