Regex is the number of 1-3 digits after a known string in Ruby
I need to match the numbers in the following strings. It is possible they may be part of longer strings with other numbers in them, so I specifically want to match the number(s) occuring directly after the space which follows the text 'Error Code':
Error Code 0 # Match = 0
Error Code 45 # Match = 45
Error Code 190 # Match = 190
Also possible:
Some Words 12 Error Code 67 Some Words 77 # Match = 67
I'm using someString.match(regEx)[0] but I can't get the regex right.
/(?:Error Code )[0-9]+/
This uses a non-capturing group (not available in all regex implementations.) It will say, hey the String better have this phrase, but I don't want this phrase to be part of my match, just the numbers that follow.
If you only want between 1 and three digits matched:
/(?:Error Code )[0-9]{1,3}/
With Ruby you should run into very few limitations with your regex. Aside from conditionals, there isn't very much Ruby's regex cannot do.
