I have a Markdown file README.md that contains HTML elements, such as an <img> tag with attributes id and src. I want to update the attributes of this HTML element programmatically using Python.
For example, I want to update the src attribute of a tag with id="updatable". I’ve successfully extracted the src attribute using BeautifulSoup, but I’m stuck when trying to update it.
Here’s my current approach:
import markdown
from bs4 import BeautifulSoup
import json
import chardet
def get_encoding_type(file_path):
with open(file_path, 'rb') as f:
sample = f.read(1024)
cur_encoding = chardet.detect(sample)['encoding']
return cur_encoding
with open("README.md", "r", encoding = get_encoding_type("README.md"),errors='ignore') as f:
markdown_content = f.read()
html_content = markdown.markdown(markdown_content)
parser = BeautifulSoup(html_content, "html.parser")
img_id = parser.find("img",{'id':'updatable'})
try:
img_source = img_id['src']
print(img_source)
except:
print("No image found")
So far, I’ve managed to extract the src attribute, but I’m unsure how to update it.

Reset to default 0You could simply assign the new value to the src attribute:
soup.find("img",{'id':'updatable'})['src'] = 'new_value'
Example:
from bs4 import BeautifulSoup
html = '<html><body><img id="updatable" src="old_value"/></body></html>'
soup = BeautifulSoup(html)
img = soup.find("img",{'id':'updatable'})
img['src'] = img['src'].replace('old','new')
print(soup)
Output:
<html><body><img id="updatable" src="new_value"/></body></html>
