Two problems here: str.replace doesn't use regular expressions. You'll have to use the re module to use regexps. (the re.sub function to be precise) '.' matches a single character. Any character, but only one. '.*' matches as many characters as possible. This is not what you want, since it will match everything between the *first* <? and the *last* ?>. You want non-greedy matching. '.*?' is the same thing, without the greed. > > # add ID > print 'adding unique page_id' > src_data = ( '<!-- %d -->' % id ) + src_data > id += 1 > > # add template variables > print 'adding counter template variable' > src_data = src_data + ''' <h4><font color=green> Αριθμός > Επισκεπτών: %(counter)d </font></h4> ''' > # i can think of this but the above line must be above </ > body></html> NOT after but how to right that?!? You will have to find the </body> tag before inserting the string. str.find should help -- or you could use str.replace and replace the </body> tag with you counter line, plus a new </body>. > > # rename old php file to new with .html extension > src_file = src_file.replace('.php', '.html') > > # open newly created html file for inserting data > print 'writing to %s' % dest_f > dest_f = open(src_f, 'w') > dest_f.write(src_data) # write contents > dest_f.close() > > This is the best i can do. No it's not. You're just giving up too soon. -- http://mail.python.org/mailman/listinfo/python-list
