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)
src = open('2.htm').read() pattern = 'Editplus allow me to double click at the output printed and jump to the exact position using the given lineno, offset.
([^<]+)' # or anything else for m in re.finditer(pattern, src): start = m.start() lineno = src.count('\n', 0, start) + 1 offset = start - src.rfind('\n', 0, start) word = m.group(1) print "2.htm(%s,%s): %s" % (lineno, offset, word)
