I need to parse a string from this:

CN=ERT234,OU=Computers,OU=ES1-HER,OU=ES1-Seura,OU=RES-ES1,DC=resu,DC=kt,DC=elt

To this:

ES1-HER / ES1-Seura

Any easy way to do this with regex?

At least try to solve the problem yourself first, this is not a resource that magically generates code for badly described problems. – nic Nov 27 '13 at 12:05
    
Why are you regexing LDAP strings? There's python modules that will parse that for you. – beerbajay Nov 27 '13 at 12:07
    
Hi, thanks for answers. I use a different python version embedded in a external program. – user2023042 Nov 27 '13 at 12:11

>>> import re    
>>> s = 'CN=ERT234,OU=Computers,OU=ES1-HER,OU=ES1-Seura,OU=RES-ES1,DC=resu,DC=kt,DC=elt'
>>> re.findall('OU=([^,]+)', s)
['Computers', 'ES1-HER', 'ES1-Seura', 'RES-ES1']
>>> re.findall('OU=([^,]+)', s)[1:3]
['ES1-HER', 'ES1-Seura']
>>> ' / '.join(re.findall('OU=([^,]+)', s)[1:3])
'ES1-HER / ES1-Seura'

Don't use str as a variable name. It shadows builtin function str.
