并没有出现数据只显示了“进程已结束,退出代码0”这段文字(标签-xml|关键词-for)

import requests
from lxml import etree

url = "https://beijing.zbj.com/search/f?r=1%22
resp = requests.get(url)
html = etree.HTML(resp.text)
divs = html.xpath("html//div")
for div in divs:
price = div.xpath("./div/div[3]/div[1]/span/text()")[0]
print(price)

运行这一段代码后，并没有出现数据
只显示了
“进程已结束,退出代码0”
这段文字，怎么回事

这说明divs是空的
