Initial Comment:
with perl:

$tag = '<abc xyz="def/ghi">';
$tag =~ /<(\/|\?)?(.*?)(\/|\?)?>/;
print "1=$1\n";
print "2=$2\n";
print "3=$3\n";

you get:

1=
2=abc xyz="def/ghi"
3=

with python
(ActivePython 2.1, build 210 ActiveState
based on Python 2.1 (#15, Apr 19 2001, 10:28:27)
[MSC 32 bit (Intel)] on win32):

import re
p = re.compile("<(/|\?)?(.*?)(/|\?)?>")
tag = '<abc xyz="def/ghi"><test>'
m = p.search(tag)
print '1='+str(m.group(1))
print '2='+str(m.group(2))
print '3='+str(m.group(3))

you get:

1=None
2=abc xyz="def/ghi"
3=abc xyz="def/
