I'm trying to extract part of html code from a tag to a tag code begins
with <span class="boldyell ow"><B><U> and ends with
TD><TD> <img src="http://whatever/some.gif"> </TD></TR></TABLE>
I was thinking of using a regular expression however I having hard time
getting the desired string. I use
htmlSource = urllib.urlopen( "http://address/")
s = htmlSource.read ()
htmlSource.clos e()
to get the html into a string, now I want to match string s from a <span
class Tag to <img src="http://whatever/some.gif"> </TD></TR></TABLE> and
store that into a new string.
Thanks 3 6002

For tag soup, use BeautifulSoup:
<URL:http://www.crummy.com/software/BeautifulSoup/>
Available as a package in Debian, probably other decent OSen also.

Except he's trying to extract an apparently random part of the
file. BeautifulSoup is a wonderful thing for dealing with X/HTML
documents as structured documents, which is how you want to deal with
them most of the time.
In this case, an re works nicely: import re s = '<span class="boldyell ow"><B><U> and ends with TD><TD> <img src="http://whatever/some.gif"> </TD></TR></TABLE>' r = re.match('<span class="boldyell ow"><B><U>(.*)T D><TD> <img src="http://whatever/some.gif"> </TD></TR></TABLE>', s) r.group(1)
' and ends with '
String.find also works really well:
start = s.find('<span class="boldyell ow"><B><U>') + len('<span class="boldyell ow"><B><U>') stop = s.find('TD><TD> <img src="http://whatever/some.gif"> </TD></TR></TABLE>', start) s[start:stop]
' and ends with '
Not a lot to choose between them.

Thanks Mike that is just what I was looking for, I have looked at
beautifulsoup but it doesn't really do what I want it to do, maybe I'm
just new to python and don't exactly know what it is doing just yet.
However string find woks. Thanks

I took a quick look in the archives, but didn't find an answer
to this one.
I'd like to display a list of HTML files in a directory, showing the
author's name between brackets after the file name. I can successfully
extract the TITLE section, but no luck with the AUTHOR part. Any idea
why?

Hi everyone,
I try to write a simple web crawler. It has to do the following:
1) Open an URL and retrieve a HTML file.
2) Extract news headlines from the HTML file
3) Put the headlines into a RSS file.
For example, I want to go to this site and extract the headlines:
www.unstrung.com/section.asp?section_id=86

include('page.htm?id=12&foo=bar');
But since I can't (and don't want to make another seperate HTTP request
with include('http://...')); I was wondering if there's a function
similar to extract(); that can handle a query string as input, so that I
could:
$id = 12;
$foo = 'bar';
include('page.htm');

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
