I have a html file where I would like to insert a <meta> tag between the <head> & </head> tags using python. If I open the file in append mode how do I get to the relevant position where the <meta> tag is to be inserted?

6What you describe isn't appending, it is inserting (as you yourself state). Append mode allows you to add to the end of the file, and thus won't help here.Scott Hunter– Scott Hunter2013年10月01日 18:26:35 +00:00Commented Oct 1, 2013 at 18:26

Use BeautifulSoup. Here's an example where a meta tag is inserted right after the title tag using insert_after():
from bs4 import BeautifulSoup as Soup
html = """
<html>
<head>
<title>Test Page</title>
</head>
<body>
<div>test</div>
</html>
"""
soup = Soup(html)
title = soup.find('title')
meta = soup.new_tag('meta')
meta['content'] = "text/html; charset=UTF-8"
meta['http-equiv'] = "Content-Type"
title.insert_after(meta)
print soup
prints:
<html>
<head>
<title>Test Page</title>
<meta content="text/html; charset=UTF-8" http-equiv="Content-Type"/>
</head>
<body>
<div>test</div>
</body>
</html>
You can also find head tag and use insert() with a specified position:
head = soup.find('head')
head.insert(1, meta)

One way to do it: with open("/file/name.html", "r") soup = Soup(file) title = soup.find('title') meta = soup.new_tag('meta') meta['content'] = "text/html; charset=UTF-8" meta['http-equiv'] = "Content-Type" title.insert_after(meta) with open("/file/name.html", "w") as f: f.write(str(soup)) It worked for me, thanks.
