| Feb 1, 2012 at 17:44 | comment | added | TheSavo | I think I may have found the answer my self. If it run the regex: ([0-9]+) , which leads with a space, and trails with a space will only find a number pattern that has a space in front and behind it. Since valid Code Numbers will have a decimal, this will only find, what would be the extra digits. I wrapped it in parens, and use a back reference, lead it with an underscore, and trail it with a space. '\1 ' So it will attach the extra digits to the parent, and delimit the whole string with a space. I then add and undersore to my regex pattern like so. "([0-9]+\.[0-9]+) " | |
| Feb 1, 2012 at 16:39 | comment | added | TheSavo | The regex that I am using is listed, and highlighted. The list is space delimited, because it was copied from a webpage. In my example data sets, a valid CODE number shouldn't have a space in it. However my employer has made exceptions to that rule. Anytime there is a CODE number with a space, it typically has one space followed by two numbers. But there have been examples where it trailed with one or three digits. But those are even rarer. | |

| Feb 1, 2012 at 14:54 | comment | added | EBGreen | If it is space delimited but the pattern needs to sometimes (but only sometimes) include spaces, then you will need to rigorously define when a space needs to be included and when it does not. If the definition is precise and accurate enough, then you could probably write a regex, but without that definition it isn't really possible to write one that would be 100% correct. | |
