Starting with SWAT 20.05 version, you can use regular expressions definitions to specify the format of a character field. The definition is added in the 'extendedFormat' attribute in the designer.

We support the following masks:

• static masks (ex: 99-9999999 or (999) 999-9999)
• dynamic masks (ex: aa-9{1,4} - the 9 digit can occur 1 to 4 times)
• Regex expressions (ex: [0-9]*)

Masking definitions:

• 9 - numeric
• a - alphabetical
• * - alphanumeric

Examples for the extendedFormat attribute on character fields to specify the format:

• extendedFormat: aa-9999
• extendedFormat: aa-9 {4}
• extendedFormat: regex:[0-9]*
