In my career, about 90% of the paid programming has been maintenance.
As such, any time RegEx comes up, I am almost filled with dread: RegEx is terrible, overly limited, often part of a system that easily evolves beyond the constraints that are implied with RegEx (that of being a "regular language"). -- I would go so far as to even advise things like "compiler recognizers" *not* use RegEx.

I've found that an actual parsing system is far preferable to RegEx. In Byron, parsing is trivial:
  I : Integer renames Integer'Wide_Wide_Value( This_Value );
Where "This_Value" is the string in question.
Is it cheating to use the 'Value Attribute? Possibly, but this also provides for consistency between 'Value and the associated integer-value.
