我需要创建一个新字符串，内容是一个websi的标题

Question

我原以为像（1）这样的东西会起作用，但它抛出了一个错误。有什么想法或建议吗？你知道吗

（一）

versionPreCheck = lxml.html.parse("URL")
versionCheck = versionPreCheck.find(".//title").text

LatestVersion = (versionCheck.read())

错误：

Traceback (most recent call last):
  File "python", line 132, in <module>
  File "src/lxml/etree.pyx", line 3426, in lxml.etree.parse
  File "src/lxml/parser.pxi", line 1839, in lxml.etree._parseDocument

OSError: Error reading file 'bazorkversion--grify.repl.co': failed to load external entity "bazorkversion--grify.repl.co"

标题如下：

https://bazorkversion--grify.repl.co/ 标题是字符串“PreAlpha 3” （它出现在浏览器选项卡的顶部，站点的favicon旁边）

Answer 1

You aren't the only one receiving this error，它可能是lxml中的一个故障。你知道吗

相反，您可以尝试使用另一个web抓取模块，如BeautifulSoup，以及requests模块来接收来自URL的请求：

>>> import requests
>>> from bs4 import BeautifulSoup as BS
>>> r = requests.get('https://bazorkversion grify.repl.co/')
>>> soup = BS(r.text, 'lxml')
>>> soup.title.text
'PreAlpha 3'
