Question

I have the following function which is supposed to read a .html file and search for <input> tags, and inject a <input type='hidden'> tag into the string to be shown into the page.
However, that condition is never met:( e.g the if statement is never executed. ) What’s wrong with my regex?

 def print_choose( params, name ):

   filename = path + name
   f = open( filename, 'r' )
   records = f.readlines()
   print "Content-Type: text/html"
   print
   page = ""
   flag = True
   for record in records:
        if re.match( '<input*', str(record) ) != None:
            print record
            page += record
            page += "<input type='hidden' name='pagename' value='psychology' />"
        else:
            page += record

   print page

Thank you

Answer 1

re.match starts at the very first char in the string. Are you sure you don’t want re.search, which can match patterns in the middle of your string?
