repeating regular expressions in one string

[Shane]

Hi folks,

I'm new to regular expressions (and a novice at Python) but it seems to be the tool I need for a particular problem. I have a bunch of strings that looks like this:

'blahblah_sf1234-sf1238_blahblah'

and I would like to use the re module to parse all the 'sfXXXX' parts of the string. Each 'sfXXXX' needs to be its own string when I am through. How do I compile a regular expression that looks for more than one instance? Currently my expression looks like this:

myString = re.compile('sf[0-9][0-9][0-9][0-9]')

This works great for finding the first instance of 'sfXXXX'. I hope that was clear :)

Thanks,

Shane
