我有一个 html 代码，其中有一个由另一个程序生成的 json 字符串，并且整个 json 字符串在 html 代码中进行了注释。但是有一些重要的信息必须从 json 中解析出来。我可以做些什么来将注释的 json 字符串也转换为 html 格式，以便它成为我可以解析的正确 html 代码。

这是输入样本。由于字符限制，我剥离了一些代码。

<!DOCTYPE html> 
 <!--[if lt IE 7]> <html lang="en" class="ie ie6 lte9 lte8 lte7 os-win"> <![endif]-->
 <!--[if IE 7]> <html lang="en" class="ie ie7 lte9 lte8 lte7 os-win"> <![endif]-->
 <!--[if IE 8]> <html lang="en" class="ie ie8 lte9 lte8 os-win"> <![endif]-->
 <!--[if IE 9]> <html lang="en" class="ie ie9 lte9 os-win"> <![endif]-->
 <!--[if gt IE 9]> <html lang="en" class="os-win"> <![endif]-->
 <!--[if !IE]><!--> <html lang="en" class="os-win"> <!--<![endif]-->

我尝试取出 json 部分并尝试通过

>>> json1 = json.loads(f1)

Traceback (most recent call last):
  File "<pyshell#26>", line 1, in <module>
    json1 = json.loads(f1)
  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

您可以使用 解析来自 html 的注释，然后通过模块lambda text:isinstance(text, Comment)加载 json 字符串。json这是一个例子：

import json
from bs4 import BeautifulSoup, Comment

soup = BeautifulSoup("""
<table>
<tr>
   <td><table><tr><td>1</td></tr><tr><td>2</td></tr></table></td>
</tr>
<!--

{"test": [1,2,3]}

-->
<tr>
   <td><table><tr><td>3</td></tr><tr><td>4</td></tr></table></td>
</tr>
</table>
""")

comments = soup.find(text=lambda text:isinstance(text, Comment))
comments = json.loads(comments)
print comments['test']

印刷：

[1,2,3]

希望有帮助。
