Copy xml content from webpage and save to locally without special characters

[snippsat]

My html file has a few lines of PHP at the top, but is mainly html.

The output opens as .xml in my browser, not as a webpage

If the .xml it's genrated it will be a string.
Then need to pass that string to BS,and not the url.
Again there is nothing i can run ans test with what you post.

from bs4 import BeautifulSoup

# Your XML content as a string
xml_content = """
<?xml version='1.0' encoding='UTF-8'?><IM415 xmlns="http://www.ros.ie/schemas/customs/IM415">

# Now use lxml as parser
soup = BeautifulSoup(xml_content, 'lxml')
print(soup.prettify())

# Save the modified XML to a file
with open('test.xml', 'w', encoding='utf-8') as fp:
    fp.write(soup.prettify())
