嗨，我想从下面给出的html中抓取parsel编号。我正在尝试使用美丽，但我什么也没得到。 我尝试了几个选择器，但没有任何效果。我可能会遗漏任何细节。如果有人知道如何选择特定的
import requests,bs4
from lxml import html
s = requests.Session()
r = s.get('http://69.160.37.111/assessor/taxweb/account.jsp?accountNum=R032229', cookies={'isLoggedInAsPublic': 'true'})
tree=html.fromstring(r.content)
res=bs4.BeautifulSoup(r.content,'lxml')
parsel=res.select('table.accountSummary table tbody')
print(parsel)
这是HTML：

我写了硒代码，但是处理这么多数据非常慢。如果有人在这个方面指导我，我会很高兴
答案 0 :(得分：2)
res.select('table.accountSummary table tbody td')[0]
res.select('table.accountSummary table tbody td')[4]
res.select('table.accountSummary table tbody td')[5]
输出
'Parcel Number 71200000'
'Owner Name COLOTERRA DEVELOPMET LLC'
'Owner Address 1711 TUNA CANYON RD TOPANGA, CA 90290-3438'
如果只想获取数据，则可以使用find方法
res.select('table.accountSummary table tbody td')[0].find(text=True, recursive=False)
res.select('table.accountSummary table tbody td')[4].find(text=True, recursive=False)
res.select('table.accountSummary table tbody td')[5].find(text=True, recursive=False)
输出
' 71200000'
' COLOTERRA DEVELOPMET LLC'
' 1711 TUNA CANYON RD '
