@Joseph: thanks, however, based on my task I feel like grep is more natural, like ghostdog74 suggested. Just need to figure out how to make grep output the capture groups only, not the whole match.

Just a note, but the plus sign '+' means 'one or more' which would remove the need for repeating yourself in the patterns. So, "[0-9][0-9]*" would become "[0-9]+"

@RandomInsano: In order to use the +, you would need to escape it or use the -r option (-E for OS X). You can also use \{1,\} (or -r or -E without the escaping).
