Question

我的目标是使用RegEx扫描电子邮件中的单词＆＃34; trade＆＃34;然后打印找到它的整行。

我成功使用RegEx捕获此HTML文档中的其他数据（例如物种，重量，价格等），以及成功识别单词＆＃34; trade＆＃34;，但是我没有打印出它所在的整条生产线。我确实尝试使用BeautifulSoup来实现这个目标，但是这样做有很多困难。

理想情况下，我想捕捉和打印“＆＃34; trade＆＃34;找到了。以下是我用来尝试识别＆＃34; trade＆＃34;的代码。并打印它上面的行：

with open(file_path, 'r') as f:
        email = f.read()
        pattern = re.search(r'\btrade\b',email).group(0)
        match = re.search(r'\btrade\b', email)
        if match:
            for line in email:
                print("TRADE STUFF:",line)

请注意，我尝试过各种方法，例如print("TRADE STUFF:", line.splitlines())以及print("TRADE STUF:", line.stripped_strings)，但都没有成功。

感谢您的帮助。

Answer 1

我会这样做：

with open(file_path, 'r') as f:
   while 1:
      line=f.readline()
      if not line:
         break
      if "trade" in line.lower():
         tags=line.replace('>','<').split('<')
         for tag in tags:
            if "trade" in tag.lower():
               print("TRADE STUFF: ",tag.strip())

Answer 2

切换'for'循环和'if'语句，如下所示：

for line in email:
    if match:
       print("TRADE STUFF: ", line)
