You could write it simply like that:
Python> s = '<srm:socket portNumber="138" tcpORudp="UDP"
address="64.41.134.60"/>'
Python> re.sub('".*?"','"%s"',s,2)
'<srm:socket portNumber="%s" tcpORudp="%s" address="64.41.134.60"/>'
Python> re.sub('".*?"','"%s"',s,2) % ('1000', 'TCP')
'<srm:socket portNumber="1000" tcpORudp="TCP" address="64.41.134.60"/>'
Or you could exploit the fact that you can use a function instead of a
simply string as substitution; in that function you can do really
complicated things.
