为文本数据抓取网站 html 时出现 lxml 错误。尝试了几次迭代

lxml errors with scraping website html for text data. Tried several iterations

我正在尝试从 https://www.congress.gov/members 网站获取国会议员的文本属性。我对此很陌生。我遵循了 youtube 上的教程,认为我非常接近。

这是我试图获取的 html 信息的一个片段。文本以粗体显示。

这是我认为最接近我的语法(使用 python 2.7 - 工作限制):

import requests, lxml
import lxml.html
#from bs4 import BeautifulSoup

html = requests.get('https://www.congress.gov/members?q=%7B%22congress%22%3A%22117%22%2C%22chamber%22%3A%22Senate%22%7D')
doc = lxml.html.fromstring(html.content)

house = doc.xpath('//div[@id="houseMemberNavigator"]')[0]

print(house)#got printed element div

members = house.xpath('.//select[@id="members-representatives"]/text()')
#returns ['\n        ', '                        ']

print(members)

我确定这是我的语法,但一直无法解决....

使用BeautifulSoup

soup = BeautifulSoup(html.text, 'lxml')
[data.text for data in soup.find(id='members-representatives').select('option[value]')]
