But is there a precise criteria that you can use to distinguish IDs from other numbers? What if it said "Blah Blah 100m can be taken into consideration 1234556", 100 isn't an ID but would still be matched.

Hey, Thanks for the reply...It surely works in all above cases, but my data is really pretty mismanaged and I do not find any specific criteria to match something. Since this is a regression tool it could have any kind of errors made from user's end in the syntax of putting these IDs and I need to catch them :'(. You are right about "What if it said "Blah Blah 100m can be taken into consideration 1234556", 100 isn't an ID but would still be matched." case... Even I am funnily doubtful about the same. Seems like an unending approach. Thanks again!	[reply]
