Hi, I am trying to to parse this url:


Using BeautifulSoup(data, 'html.parser') the content all looks like this:

/Mw==','w6xpw6bCnMOmfsKr','wobCrcKu','w6nDrMKAZWU=','w4HDkhDDvsKeYcOj','ccOwUVbDkQ==','RVobC8OHPQw=','wpJGfMOn','w4HDuz

But when I downloaded the file to my local drive to run the diagnose function, it worked fine:

Diagnostic running on Beautiful Soup 4.10.0 Python version 3.8.3 (default, Jul 2 2020, 11:26:31) [Clang 10.0.0 ] Found lxml version 4.6.3.0 Found html5lib version 1.1 Trying to parse your markup with html.parser Here's what html.parser did with the markup: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <!-- saved from url=(0067)http://www.pbc.gov.cn/en/3688229/3688335/3730267/4380809/index.html --> <html> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type"/> <link href="./Announcement on Open Market Operations No.216 [2021]_files/default.css" id="lhgdialoglink" rel="stylesheet"/> <title> Announcement on Open Market Operations No.216 [2021] </title> <meta content="2021-11-05 11:00:11" name="页面生成时间"/> <meta content="2021-10-21 17:38:26" name="缓存清理时间"/> <meta content="7.9.5" name="easysite版本"/> <meta content="Announcement on Open Market Operations No.216 2021" name="keywords"/> <meta content="Announcement on Open Market Operations No.216 2021 初始化频

I was hoping to find out why I couldn't read direct from the url, and if there is a way to resolve that.

Thank you.

This is the content as it is served from the pbc.gov.cn server. You can verify this with this curl command:


Or with this Python script which uses no Beautiful Soup code:

from urllib.request import urlopen

When you use a web browser to download this web page, you end up with the HTML that's generated after your web browser runs a lot of Javascript to decode an obfuscated web page. To get that final web page in a way that you can access from Python, I recommend using a scriptable web browser like Selenium, which will run the Javascript for you.
