试图从列表中刮取数据，但由于某些原因，它返回空。类似的代码在其他网站上也起到了作用，我很困惑为什么它在这个网站上不起作用。请帮忙！

import requests
from lxml import html

start_url ="https://www.anybusiness.com.au/search?page=1&sort=date-new-old"
res = requests.get(start_url)
tree = html.fromstring(res.content) 

# Retrieve listing title

title_xpath = "/html/body/div[2]/section/div[2]/div/div[2]/div[2]/div/a/div/div/text()"
title_value= tree.xpath(title_xpath)

print(title_value)
>> []

python lxml web-scraping
