Hello again,

  I have one more question you hopefully might be able to help me with.

  I am using the following to extract the words and sentences out of the
documents, but it seems like the last character is often missing. Here
are a few lines that I would like to extract from:

=09<li type=3Dcircle><a href=3Dhttp://www.kvasir.no/query?what=3Dno&q=3Dcoo=
p+byggmix
[17/Aug/2004:09:44:22 +0200]&cf=3Dspy target=3D"_top">coop byggmix
</a><a href=3Djavascript:onClick=3DlaunchWarning('/nokkelhullet/o.html')><i=

</a>
<br><li type=3Dcircle><a

-no
[17/Aug/2004:09:44:21 +0200]&cf=3Dspy target=3D"_top">bademilj=F8
</a>

from here I want:
coop byggmix
christiano ronaldo
erop
Birgita S=F8strene
bademilj=F8


and the code I use to extract is:

rawstr =3D r"""target=3D"_top">(.*?)\n</a
"""
compile_obj =3D re.compile(rawstr,  re.IGNORECASE| re.MULTILINE| re.VERBOSE=
)
matchstr =3D side.read()
liste =3D compile_obj.findall(matchstr)

The page that I get the info from is updated continously and can be found
at http://search.kvasir.no/nokkelhullet/myspy/ . When I read the output
the last character in the sentences/words are often missing. However, I
have not been able to find a pattern of which sentences/words that misses
the last character. Only that approximately 1 out of 5 does so.

Is there something with the code that can explain why? Is there something
I can change to get the whole string that I am looking for?

Thanks in advance,
=D8yvind
