抱歉，我之前给出的正则表达式中有一个错误。在正则表达式中，括号需要进行转义，所以在你的模式中的两个括号需要改为`\(`和`\)`。以下是修改后的代码： ```python import re html = ''' <html> <meta http-equiv="Content=-Type" content="text/html; charset=utf-8"/> <head> <link href="http://192.167.1.101/hint.css" rel="stylesheet"></link> </head> <body>[talkid:137031381]2014年4月20日 03:55:45 , 2323234 在群 20011 中发言我们已经是dffwerwer天吧！ [talkid:137031382]2014年4月22日 04:45:45 , 2323234 在群 20011 中发言音频 :[<a href="files/24434sfsfsjdfrhf_n.m4a"]>音频</a> [talkid:137031383]2014年4月23日 04:55:45 , 2323234 在群 20011 中发言图片 :[<a href="files/f/f123ftrtrhf_n.jpg"]>图片</a> [talkid:137031384]2014年4月24日 05:55:45 , 2323234 在群 20011 中发言我们已方式方法方式 [talkid:137031385]2014年4月25日 06:55:45 , 2323234 在群 20011 中发言我而对方是否的天吧！ </body> </html> ''' pattern = r'\(发送|中发言\)\s*(.*?).*?(音频 :|图片 :).*?(\[.*?\])' matches = re.findall(pattern, html, re.DOTALL) for match in matches: content = match[0] content_type = match[1] file_link = match[2] if content_type == '音频 :': print(f"音频链接地址: {file_link}") elif content_type == '图片 :': print(f"图片链接地址: {file_link}") else: print(f"发言字段: {content}") ``` 请尝试运行修改后的代码，并检查是否有任何错误。如果还有问题，请告诉我。
