Problem
Our field matching heuristic operates on a 'first match wins' basis[1], meaning the first regex match always wins. This approach often causes issues that when a field actually will match multiple regexpression but we select the wrong one (first one)
Possible Solution
We could implement a more sophisticated heuristic that considers matches from all regular expression and then selects the most appropriate one based on context from surrounding fields. The problem is that this solution might be quite complicated
A Simplified Version of the Possible Solution
We could categorize our matches into "credit card" and "address" groups. A field could match a regex from both categories, but by default, we would still use the field name from the first match. However, if the field type of the previous field differs from the type of the first match, and given that fields of the same type are typically close together, we could use the field name from the "second" match instead.
Drawback
If there are both credit card and address sections in a form, we might use the wrong fieldn ame when the field is in the beginning of the second section
