ordt:redact-regex( $column as item(), $options as map:map? ) as map:map
Summary
This function redacts a string column by applying a regular expression. This function can be used with op:bind or op:select.
| Parameters | |
|---|---|
| $column | The name of the column to be redacted. This can be either a string or the return value from op:col, op:view-col, or op:schema-col. |
| $options | The options for masking the value the column. |
Usage Notes
The regular expression is specified similar to the fn:replace function. The options consist of the following required properties:
- pattern: a regular expression in XPath syntax matching the values of the column to be modified.
- replacement: the replacement value, which may use captured groups to preserve parts of the matched value.
