Need Regex helpby cochrasc (Initiate) |

cochrasc has asked for the wisdom of the Perl Monks concerning the following question:
Hey all. I stink at regexes, so I thought I would grab some help. I would normally use a split to do something like this, but the data isn't always consistent, so I think a regex is my only option. If there are any other options, I'd be happy to hear them. Here's the dealy....I'm trying to break down a string that can contain several (unknown) instances of 5 pieces of data. Here's an example of one that contains 3 instances: The first instance starts with "error", the 2nd "three" and the 3rd "fixv". Notice that the fixv instance doesn't have "{}" around the 4th and 5th pieces of data like the other 2 do...this is my problem and why I can't use split. Also note that the lack of "{}" can occur in any of the instances, not just the 3rd. So...in a nutshell...I'm trying to pull out the 3 instances into an array which I can then split (or use another regex) to get my 5 pieces of data from each. The data itself is separated by spaces (with data containing a space encompassed with {}), so in instance 1, the 5 pieces would be: I hope this makes sense...it's difficult to explain. Thanks in advance for any help.
