我有两个 xpath，其中只有一个正确地从下面的 url 中提取职位。知道为什么 xpath1(我使用 Chrome 的“检查元素/复制 XPath”功能发现它)不起作用，而 xpath2 起作用吗？
import requests
from lxml import html
url = 'http://www.mynextmove.org/find/browse?c=54'
xpath1 = '//*[@id="content"]/table[1]/tbody/tr/td[1]/a/text()'
xpath2 = '//a[contains(@href, "profile")]/text()'
page = requests.get(url)
tree = html.fromstring(page.text)
jobs = tree.xpath(xpath2)
print 'jobs:', jobs
xpath1 返回 []，即空列表。
xpath2 返回 ['人类学家'、'考古学家'、...]
最佳答案
没有 tbody 它看起来像将其更改为:
`xpath1 = '//*[@id="content"]/table[1]/tr/td[1]/a/text()'`
并尝试一下。
当我这样做时，这就是我得到的:
In [31]: tree.xpath(xpath1)
Out[31]:
