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

Question

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 lt form gt Form 1 lt  form gt  some text    lt form gt Form 2 lt  form gt  more text   matchObj   re search   lt form gt       lt  form gt    line  re S  print matchObj group 1    Output  Form 1   I need it to output every form content he found  not just first one

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 lt form gt Form 1 lt  form gt  some text    lt form gt Form 2 lt  form gt  more text   for match in re finditer   lt form gt       lt  form gt    line  re S       print match group 1

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 lt form gt Form 1 lt  form gt  some text    lt form gt Form 2 lt  form gt  more text   matches   re findall   lt form gt       lt  form gt    line  re DOTALL  print matches     Output    Form 1    Form 2

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
