python - 我正在尝试使用 Xpath 从电视节目中检索脚本，但它返回的是一个空列表

Question

from lxml import html
import requests

page = requests.get('http://officequotes.net/no1-01.php')
tree = html.fromstring(page.content)

complete_script = tree.xpath('/html/body/table/tbody/tr[2]/td[2]')

print(complete_script)

我希望显示整个(电视节目)脚本，但我得到的只是一个空列表。

Answer 1

您可以跳过 tbody 并直接抓取表格:

from lxml import html
import requests

page = requests.get('http://officequotes.net/no1-01.php')
tree = html.fromstring(page.content)
complete_script = tree.xpath('//table/tr[2]/td[2]//text()')
#to strip the characters from xml

results = [esc.strip() for esc in complete_script]
remove={'','&nbsp'}
results= [rem for rem in results if rem not in remove]

print(results)

但我更喜欢 BeautifulSoup 来轻松提取相同的东西

from bs4 import BeautifulSoup
import requests

page = requests.get('http://officequotes.net/no1-01.php')
soup = BeautifulSoup(page.content,'lxml')
complete_script = soup.select('table > tr > td')[2].get_text()
print(complete_script)
