download the zip file from ..../channel.zip
extract the channel.zip and read the read.txt

my code:
>>> import re
>>> value=90052
>>> comments=[]
>>> z=zipfile.ZipFile('/home/gaoy/Downloads/channel.zip')
>>> while True:
f=open('/home/gaoy/temp/%s'%value+'.txt')
comments.append(z.getinfo('%s'%value+'.txt').comment)
m=re.search('[0-9]+',f.read())
f.close()
if value:
value=m.group(0)
print value
else:
print value
break;

redundancy!

better reference code:
while True: 
    content=z.read('%s.txt'%value) 
    comments.append(z.getinfo('%s.txt'%value).comment) 
    match=findNothing(content) 
    if match: 
        value=match.group(0) 
    else: 
        break 
    print content

the final step:
print ''.join(comments)
