lxml xpath没有找到锚文本

Question

我有两个xpath，只有一个正确从下面的URL中提取作业标题。 知道为什么xpath1（我发现使用Chrome的'inspect element / copy XPath'功能）不起作用，而xpath2呢？

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返回空列表[]。

xpath2返回['人类学家'，'考古学家'，...]

Answer 1

没有tbody它看起来像它更改为：

`xpath1 = '//*[@id="content"]/table[1]/tr/td[1]/a/text()'`

并尝试一下。

这就是我这样做的结果：

In [31]: tree.xpath(xpath1)
Out[31]:
