Thanks you,

So i guess this needs to be written as:

src_data = re.sub( '<?(.*?)?>', '', src_data )

Tha 'r' special char doesn't need to be inserter before the regex here
due to regex ain't containing backslashes.

Ah yes! Damn why din't i think of it.... str.replace should do the
trick. I was stuck trying to figure regexes.

So, i guess that should work:

 src_data = src_data.replace('</body>', '<br><br><h4><font
color=green> Αριθμός Επισκεπτών: %(counter)d </font></h4></body>' )
