I am trying to find a generic method to extract information from strings like:
"id:36 sub:001 dlvrd:001 submit date:0704270919 done date:0704270919 stat ELIVRD err:000"
I would like to be able to extract the values of particular items by defining a Regex style pattern. I am a bit of a regex newbie and I am not sure how to go about this. I had thought about using StringTokenizer but some of the value names have spaces in them and unfortunately I have no control over the format of these strings.
Can you use regex expressions to 'name' specific variable sections of the patterns so that they can be extracted by a Matcher?
Any help will be very welcome, thanks

How did you handle the names with spaces in them? I have to guess the values cannot have spaces, or you'd never know where a value ends and a name begins.
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

A Regular Expression can include spaces in the Pattern e.g.

Oh, cool, you made a pattern with all known keys and got them all with one match. I was thinking of something generic to get one key:value at a time which would survive insertion of a new key:value one day but wouldn't be near as self documenting.
