Finding line number when matching text
I use python to do some text analysis.
I load all the text file into a string and match it with
a regexp. Now I want to know the line number of a match.
I can use the line number to lookup inside the text.
(in this case using EditPlus)
Editplus allow me to double click at the output printed
and jump to the exact position using the given lineno, offset.

1 2 src = open('2.htm').read() 3 pattern = '<P>([^<]+)<SUP>' # or anything else 4 for m in re.finditer(pattern, src): 5 start = m.start() 6 lineno = src.count('\n', 0, start) + 1 7 offset = start - src.rfind('\n', 0, start) 8 word = m.group(1) 9 print "2.htm(%s,%s): %s" % (lineno, offset, word)
Editplus allow me to double click at the output printed
