Hi

I have a python script that parses email headers to extract information
from them. I need to get the _last_ messageid in the 'References' field
(http://cr.yp.to/immhf/thread.html) to create a threaded view of these
emails (these messageid's are stored in a database).

Now, I can easily access the 'References' field using the python 'email'
module, but I need a regular expression to get the last messageid in the
'References' field.

Here's what I have so far:
<code>
rx_lastmesgid = re.compile(r"(<.+>$)")
lastmesgid = "".join( filter( rx_lastmesgid.match, parentid ) ) #
parentid's value is
eg:"<[e-mail]><[e-mail]><[e-mail] ail.com><[e-mail]><[e-mail]>"
lastmesgid = "".join( filter( rx_lastmesgid.match, parentid ) )
</code>

I need it to return "<[e-mail]>"

Can anyone help?

"<.*>(<.*?>)"
