[Tutor] parse text file

[Norman Khine]

hello,
thank you all for the advise, here is the updated version with the changes.

import re
file = open('producers_google_map_code.txt', 'r')
data = repr( file.read().decode('utf-8') )

get_records = re.compile(r"""openInfoWindowHtml\(.*?\\ticon:
myIcon\\n""").findall
get_titles = re.compile(r"""<strong>(.*)<\/strong>""").findall
get_urls = re.compile(r"""a href=\"\/(.*)\">En savoir plus""").findall
get_latlngs = re.compile(r"""GLatLng\((\-?\d+\.\d*)\,\\n\s*(\-?\d+\.\d*)\)""").findall

records = get_records(data)
block_record = []
for record in records:
	namespace = {}
	titles = get_titles(record)
	title = titles[-1] if titles else None
	urls = get_urls(record)
	url = urls[-1] if urls else None
	latlngs = get_latlngs(record)
	latlng = latlngs[-1] if latlngs else None
	block_record.append( {'title':title, 'url':url, 'lating':latlng} )

print block_record

i have latin-1 chars in the producers_google_map_code.txt' file and
this is the only way to get it to read the data.

is this incorrect?
