Question

how to remove text between <script>and </script>using python?

Answer 1

You can use BeautifulSoup with this (and other) methods:

soup = BeautifulSoup(source.lower())
to_extract = soup.findAll('script')
for item in to_extract:
    item.extract()

This actually removes the nodes from the HTML. If you want to leave empty tags <script></script>, you will have to work with attributes item, and not just extract them from the soup.

Answer 7

I don't know, Python is good enough to tell you a solution. But if you want to use this to disinfect user input, you have to be very careful. To delete things between them and just not all. Perhaps you can take a look at existing solutions (I suppose Django includes something like this).

Answer 8

example_text = "This is some text <script> blah blah blah </script> this is some more text."

import re
myre = re.compile("(^.*)<script>(.*)</script>(.*$)")
result = myre.match(example_text)
result.groups()
  <52> ('This is some text ', ' blah blah blah ', ' this is some more text.')

# Text between <script> .. </script>
result.group(2)
  <56> 'blah blah blah'

# Text outside of <script> .. </script>
result.group(1)+result.group(3)
  <57> 'This is some text  this is some more text.'

Answer 9

If you do not want to import any modules:

string = "<script> this is some js. begone! </script>"

string = string.split(' ')

for i, s in enumerate(string):
    if s == '<script>' or s == '</script>' :
        del string[i]

print ' '.join(string)
