The code works till last week correctly, I don't change the pattern.
Websites' contents and structure change sometimes.
My question is, can it be a problem with string encoding?
Your regex is all-ascii. So an encoding problem is very unlikely.
found = re.search( "<a
href=\"/projects/boost/files/latest/download\?source=files\"
title=\"/boost/(.*)",
data)
Did I mask the question mark and quotes
correctly?
Yes.
A quick check...
data =
urllib.urlopen("http://sourceforge.net/projects/boost/files/boost/";).read()
re.compile("/projects/boost/files/latest/download\?source=files.*?>").findall(data)
['/projects/boost/files/latest/download?source=files"
title="/boost-docs/1.56.0/boost_1_56_pdf.7z: released on 2014-08-14
16:35:00 UTC">']
...reveals that the matching link has "/boost-docs/" in its title, so the
site contents probably did change.
I have create a short script:
---------
#!/usr/bin/env python
import re, urllib2
def URLReader(url) :
f = urllib2.urlopen(url)
data = f.read()
f.close()
return data
print re.match( "\<small\ \>.*\<\/small\>",
URLReader("http://sourceforge.net/projects/boost/";) )
---------
Within the data the string "<small>boost_1_56_0.tar.gz</small>" should
be machted, but I get always a None result on the re.match, re.search
returns also a None.
I have tested the regex under http://regex101.com/ with the HTML code
and on the page the regex is matched.
Can you help me please to fix the problem, I don't understand that the
match returns None
Thanks
Phil
