Question: import os from bs4 import BeautifulSoup # Get a list of all .htm files in the HTML_bak folder html_files = [file for file in os.listdir('HTML_bak') if file.endswith('.htm')] # Loop through each HTML file for file_name in html_files: input_file_path = os.path.join('HTML_bak', file_name) output_file_path = os.path.join('HTML', file_name) # Read the input file with errors='ignore' with open(input_file_path, 'r', encoding='utf-8', errors='ignore') as input_file: input_content = input_file.read() # Parse the input content using BeautifulSoup with html5lib parser soup = BeautifulSoup(input_content, 'html5lib') main_content = soup.find('div', style='position:initial;float:left;text-align:left;overflow-wrap:break-word !important;width:98%;margin-left:5px;background-color:#FFFFFF;color:black;') # Overwrite the output file with modified content with open(output_file_path, 'w', encoding='utf-8') as output_file: output_file.write(str(main_content))  This code correctly scans HTML files in a folder and only pulls in the desired div based on style. However, there are sometimes tags within this div tag that I want to remove. Those tags appear as: <div class="gmail_quote">2010/2/11 some text here .... </div> How can I edit my code to also remove these tags with gmail_quote class? Update 8/29/23: I am copying an example HTML content to make sure my question is clear. I want to keep the contents of the <div style="position:initial.... after <body bgColor=#ffffff> and remove the contents of the <div class="gmail_quote">2010/2/11 ...  <html><body style="background-color:#FFFFFF;"><div></div></body></html><article style="width:100%;float:left; position:left;background-color:#FFFFFF; margin: 0mm 0mm 0mm 0mm; "><style> @media print { pre { overflow-x:break-word; white-space:pre; white-space:hp-pre-wrap; white-space:-moz-pre-wrap; white-space:-o-pre-wrap; white-space:-pre-wrap; white-space:pre-wrap; word-wrap:break-word;} }pre { overflow-x:break-word; white-space:pre; white-space:hp-pre-wrap; white-space:-moz-pre-wrap; white-space:-o-pre-wrap; white-space:-pre-wrap; white-space:pre-wrap; word-wrap:break-word;} @page {size: auto; margin: 12mm 4mm 12mm 6mm; } </style> <div style="position:initial;float:left;background-color:transparent;text-align:left;width:100%;margin-left:5px;"> <html><head><meta http-equiv="Content-Type" content="text/html;charset=UTF-8;"><style> .hdrfldname{color:black;font-size:20px; line-height:120%;} .hdrfldtext{overflow-wrap:break-word;color:black;font-size:20px;line-height:120%;} </style></head> <body bgColor=#ffffff> <div style="position:initial;float:left;text-align:left;font-weight:normal;width:100%;background-color:#eee9e9;"> <span class='hdrfldname'>SUBJECT: </span><span class='hdrfldtext'>lorem ipsum</span><br> <span class='hdrfldname'>FROM: </span><span class='hdrfldtext'>lorem ipsum</span><br> <span class='hdrfldname'>TO: </span><span class='hdrfldtext'>lorem ipsum</span><br> <span class='hdrfldname'>DATE: </span><span class='hdrfldtext'>2010/02/12 09:10</span><br> </div></body></html> </div> <div style="position:initial;float:left;text-align:left;overflow-wrap:break-word !important;width:98%;margin-left:5px;background-color:#FFFFFF;color:black;"><br> <html><head><meta http-equiv="Content-Type" content="text/html;charset=UTF-8;"><style> pre { overflow-x:break-word; white-space:pre; white-space:hp-pre-wrap; white-space:-moz-pre-wrap; white-space:-o-pre-wrap; white-space:-pre-wrap; white-space:pre-wrap; word-wrap:break-word;} </style></head><body bgColor=#ffffff> <div> lorem ipsum </div> <div class="gmail_quote">2010/2/11 lorem ipsum<span dir="ltr">&lt;<a style="max-width:100%;" href="lorem ipsum">lorem ipsum</a>&gt;</span><br> </body></html> </div> </article> <div>&nbsp;<br></div> 

Answer: You can modify your code to remove the div tags with the gmail_quote class by using the decompose() method of the BeautifulSoup library. This method removes a tag from the tree and then completely destroys it and its contents.  # Find and remove all div tags with class gmail_quote for tag in main_content.find_all('div', {'class': 'gmail_quote'}): tag.decompose()  Add this code below your main_content line. This should remove all div tags with the gmail_quote class from the main_content before writing it to the output file.
