You are reading the data by line using readlines(). You only search each line once. regex.findall() or regex.finditer() would be a better choice than regex.search(). You might also be interested in sgmllib-based solutions to this problem, which will generally be more robust than regex-based searching. For example, see http://diveintopython.org/html_processing/extracting_data.html http://www.w3journal.com/6/s3.vanrossum.html#MARKER-9-26 Kent > > Thank you very much for your help. > > > import re > from urllib import urlopen > > fileObj = urlopen("http://name_of_the_page";) > links = [] > regex = re.compile ( "((/dog/)[^ \"\'<>;:,]+)",re.I) > > for a in fileObj.readlines(): > result = regex.search(a) > if result: > print result.group() > > > > > ______________________________________________ > LLama Gratis a cualquier PC del Mundo. > Llamadas a fijos y móviles desde 1 céntimo por minuto. > http://es.voice.yahoo.com > _______________________________________________ > Tutor maillist - Tutor@python.org > http://mail.python.org/mailman/listinfo/tutor > > _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
