Question

The last time I used a regular expression was 2 years ago and even then it wasn’t something I considered to be the simplest of things!

Could anybody tell me how I would go about splitting this text into three groups (qty, name, price)?

  1 Corn Dog             5.00
  3 Corn Dog            15.00
    @ 5.00
  2 Diet Cola            4.00
    @ 2.00

I’ve attempted it myself following http://www.regular-expressions.info/reference.html but the symbols are getting overwhelming! I’m tempted to start doing some funky string manipulation as a plan B.

I’m using Objective-C so I’ll probably use NSPredicate to execute the expression.

I would start with ^\([:digit]+\)[:space:]*\(.*\)[:space:]\([:digit:]+\.[:digit:]{2}\)

Remember that different regex compilers have different rules about backslashing ()[]*+|
