Hi Kent, Sorry I didn't make my question clearer. Bascially I want to replace this line:
<srm:socket portNumber="138" tcpORudp="UDP" address="64.41.134.60"/> With: <srm:socket portNumber="2" tcpORudp="TCP" address="64.41.134.60"/> So the regex grouping are that I want to keep portNumber= and tcpORudp= and replace the values. Which will be varibles in my code. The question is more on the string formatting in the replace. How do use two %s in one statement? i.e.: re.sub('\1 %s \2 %s' % var1 % var2, line) Thanks again! > Hello, > > I'm trying to replace some strings in a line of text, > using some regex functions.

Hi Jerome, I don't understand your question. Can you give a complete example of the line from the file and the new line you want to create? > > Here's the line it matches in the file: > > <srm:socket portNumber="138" tcpORudp="UDP" > address="64.41.134.60"/> > > Here's the regex: > m_sock = re.compile('(portNumber=)"\d+" > (tcpORudp=)"[A-Z]+"') You have put parentheses around fixed strings, so your groups will always be the same. Is that what you want? > > My replace should look like this: > \1 "112" \2 "TCP" > (obviously "112" and "TCP" would be varibles) This looks like you want to make the string portNumber= 112 tcpORudp= TCP but that doesn't have any variable text from the original string so I think I must not understand.
