How to add a new div tag in an existing html file after a h1 tag using python

Question

I have a html file and i want to add a div tag after h1 tag. the div tag will have a anchor tag. how can i edit the existing html file using python and add the div with link this is what i want to do

<h1>
</h1>
<div> <a></a>
</div>

i tried with BeatifulSoup. got AttributeError: 'NoneType' object has no attribute 'insert_after' this error:

htmlFile ='path to html file' 
soup = Soup(htmlFile) 
headTag = soup.find('h1') 
divTag = soup.new_tag('div') 
divTag['class'] = "link" 
headTag.insert_after(divTag)

pls suggest to modify this code to add the div tag in the current html file

The parser fails because you're not passing the content of your file, but instead passing a string of the path. Thus, you are searching for a h1 tag in the path, and the parser wouldn't find it.

htmlFile = open('path to html file').read()

The full code:

with open("path to html file") as file:
    htmlFile = file.read()
    soup = Soup(htmlFile) 
    headTag = soup.find('h1') 
    divTag = soup.new_tag('div') 
    divTag['class'] = "link" 
    headTag.insert_after(divTag)
    print(soup) #This should print the new, modified html

How do you check that a tag is added or not? printing `headTag`? – aIKid Nov 05 '13 at 13:07

Try with append for the <a> tag and insert_after to add it after <h1>:

from bs4 import BeautifulSoup
import sys

soup = BeautifulSoup(open(sys.argv[1], 'r'))
h1 = soup.find('h1')
div = soup.new_tag('div')
a = soup.new_tag('a')
div.append(a)
h1.insert_after(div)
