Barcode regex
The barcode regex feature enables the user to define Inspection and Route barcode identifiers that can match multiple non-identical barcode strings.
Regular expressions (regex) are characters sequences that specify match patterns in strings. By using a regex as Inspection/Route barcode identifier, the user defines the characteristics a barcode string must have in order to match the Inspection/Route identifier.
In this way, a barcode scan can trigger a match between the barcode string and the Route/Inspection identifier even if the two strings are non-identical, making possible to link the same Inspection/Route to a group of barcode strings that share the specified characteristics.
The barcode regex identifiers must use regex syntax compatible with Java 8. For more information, refer to Validating a barcode regex identifier.
The following table shows some examples of basic string characteristics and the regex constructs to use in order to match them:
The string must include | Regex |
|---|---|
A single digit | [0-9] |
A single letter | [A-z] |
A single uppercase letter | [A-Z] |
A single lowercase letter | [a-z] |
Two letters | [A-z]{2} |
A single digit between 3-6 | [3-6] |
A single letter between C-M | [C-M] |
Any value (zero or multiple times) | .* |
Any value (three times) | .3 |
A whitespace | \s |
Text containing A or B | (A|B) |
Text containing A and B | (?=.*(A))(?=.*(B)) |
Text starting with ABC | ^ABC |
Text ending with ABC | ABC$ |
The following table shows some scenario examples and their matching regex constructs:
# | Scenario | Regex |
|---|---|---|
1 | In position 1-2-3 there are digits | ^[0-9]{3} |
2 | In position 4-5-6 there are letters | ^.{3}[A-z]{3} |
3 | Exact value of position 7-8 is ER | ^.{6}(ER) |
4 | In position 9-10 there is a number between 10 and 49 | ^.{8}[1-4][0-9] |
5 | In position 9-10 there is a number between 10 and 50 | ^.{8}([1-4][0-9]|50) |
6 | In position 9-10 there are letters between CA and LZ | ^.{8}[C-L][A-Z] |
7 | The text contains XYZ | XYZ |
8 | The text contains 12 and AB independently from the order | (?=.*(12))(?=.*(AB)) |
9 | Scenarios #1 #2 #3 #4 at same time | ^[0-9]{3}[A-z]{3}(ER)[1-4][0-9] |
10 | Scenarios #1 #2 #3 #4 #7 at same time | (?=.*([0-9]{3}[A-z]{3}(ER)[1-4][0-9]))(?=.*(XYZ)) |
11 | Scenarios #1 #3 #6 at same time | ^[0-9]{3}.{3}(ER)[C-L][A-Z] |
12 | In position 1-2-3 there are letters, followed by a dot, then a letter, a whitespace and ends with a number | ^[A-z]{3}[.][A-z]\s.*[0-9]$ |
