我下载了一个网页并将其保存为 html 格式。我想解析并获取“fullname”、“memberHeadline”、“numberOfConnections”等的值。我尝试在 Python 中使用 BeautifulSoup，但它不起作用。我也试过

>>> import json
>>> encoded_data = json.loads(f)

Traceback (most recent call last):
  File "<pyshell#14>", line 1, in <module>
     encoded_data = json.loads(f)
  File "C:\Python27\lib\json\__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "C:\Python27\lib\json\decoder.py", line 365, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "C:\Python27\lib\json\decoder.py", line 383, in raw_decode
    raise ValueError("No JSON object could be decoded")
    ValueError: No JSON object could be decoded

我不清楚文件的格式是什么。下面复制的是文件的内容。

这是一个 HTML 文件。你可以看出来，因为它以<!DOCTYPE html>（实际上，这意味着它是 HTML5）开头。

您无法加载它的原因json是因为它不是json. 你得到的异常是预期的，你的代码应该可以处理它，因为通常传递错误类型的文件是会发生的事情。

您可能希望使用lxml（可能与beautifulsoup后端一起使用）来解析它。

标头是 HTML5 的文档类型（此功能类似于 XHTML）。与 XHML 不同的是，您实际上并不需要关闭一些标签，但在这种情况下，它看起来更像是一种“隐藏 iframe 流”技术，页面将永远加载。

关于解析，我会推荐关于“解析格式错误的 html”-> 如何使用标准库在 python 中解析格式错误的 HTML 中的答案
