Python - Using regex to find multiple matches and print them out [duplicate]

I need to find content of forms from HTML source file, I did some searching and found very good method to do that, but the problem is that it prints out only first found, how can I loop through it and output all form contents, not just first one?

line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
matchObj = re.search('<form>(.*?)</form>', line, re.S)
print matchObj.group(1)
# Output: Form 1
# I need it to output every form content he found, not just first one...

Do not use regular expressions to parse HTML.

But if you ever need to find all regexp matches in a string, use the findall function.

import re
line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
matches = re.findall('<form>(.*?)</form>', line, re.DOTALL)
print(matches)

# Output: ['Form 1', 'Form 2']

Instead of using re.search use re.findall it will return you all matches in a List. Or you could also use re.finditer (which i like most to use) it will return an Iterator Object and you can just use it to iterate over all found matches.

line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
for match in re.finditer('<form>(.*?)</form>', line, re.S):
    print match.group(1)

Using regexes for this purpose is the wrong approach. Since you are using python you have a really awesome library available to extract parts from HTML documents: BeautifulSoup.
