With the re/sre module included with Python 2.4:
pattern = "(?P<id1>avi)|(?P<id2>avi|mp3)"
string2match = "some string with avi in it"
matches = re.finditer(pattern, string2match)
....
matches.groupdict()
{'id2': None, 'id1': 'avi'}
Which was expected since overlapping matches are ignored.

Has anyone ever encountered trouble with regular expressions not
capturing matches specified by parentheses? I seem to have a weird
situation where a regular expression is matching the String I'm running
it against, but none of the parenthized expressions are coming back in
the array.
I'm basically trying to pull a topic out of a bulletin board page. So
I'll run:

I'm experiencing bad performance with certain kinds of match queries. Using
a custom XPathNavigator that wraps the usual navigator I can see that many
more node visits are performed than should be required. My document looks
something like this:
<a>
<b>
<c/>
</b>
<b/>

Hi there,
I'm attempting to extract a number from a string, and I'm using the
following code:
Regex prRegexp = new Regex( @"Rank_1:\d+:(\d+)" );
MatchCollection matches = prRegexp.Matches( responseText.ToString() );

Hello,
Is there a simple flag to set to allow overlapping matches
for the findall() regular expression method? In other words,
if a string contains five occurrences of the string pattern
"cat", calling findall on the string returns a list
containing five "cat" strings. Is it possible for findall()
to just return one "cat" string?
Thanks

Hey guys and gals,
This is a followup of my "Counting all permutations of a substring"
thread (see
http://groups.google.com/group/comp.lang.python/browse_thread/thread/60ebeb7ae381b0a9/7657235b3fd3966f#7657235b3fd3966f
in Google Groups) I'm still having a difficult time figuring out the
intricacies of regular expressions and consecutive matches. Here's a
brief example:

I probably should find an RE group to post to, but my news server at
work doesn't seem to have one, so I apologize. But this is in Python
anyway :)
So my question is, how can find all occurrences of a pattern in a
string, including overlapping matches? I figure it has something to do
with look-ahead and look-behind, but I've only gotten this far:
import re
string = 'abababababababab'

how can i determine if a given character sequence matches my regex,
completely?
in java for example I can do,
Pattern.compile(regex).matcher(input).matches()
this returns True/False whether or not input matches the regex
completely.
is there a matches in python?

Dear ALL,
I'm writing some first examples to get a better understanding of XSLT/
XPATH2.0.
Please excute this code, any xml input is OK.
I'm using saxon. The example runs perfect with ALTOVA, but fails with
SAXON.
Please refere to line with element <matcheswhich is quite close to
the error.

Hi,
I cannot guess, why some XPath expressions in my code returns false and some
even errors, while the others returne true as I expected. I'am workin with VS
2008 Express Edition.
Dim xEl As XElement = <root><child1><child2/></child1></root>
Dim nav As XPathNavigator = xEl.CreateNavigator
nav.MoveToRoot()

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.
Here is my compilation command:
