Regex Extractor component (AI Flowi Workflow)
Regex Extractor extracts patterns from text using regular expressions. Place it after a Message source when you want a pattern-based extraction step.
By Ai Flowi · Published
Regex Extractor is documented in the catalogue; not production-tested by Ai Flowi. Neither a match result nor a JSON response shape is recorded in this reference.
Inputs
| Name | Type | Required | Accepted input types | Plain explanation |
|---|---|---|---|---|
input_text | str | Yes | Message | The text to search, supplied through a Message connection or the configured text field. |
pattern | str | Yes | Message | The regular expression for the search. This field also accepts Message; the export does not identify the regex engine or flags. |
Outputs
| Display name | Name | Type | What to connect |
|---|---|---|---|
| JSON | data | JSON | The JSON-typed extraction output. Its object keys and match layout are not documented. |
| Message | text | Message | The Message-typed extraction output. Its formatting and separator rules are not documented. |
When to use Regex Extractor
Choose Regex Extractor to look for a repeatable pattern inside text, such as a labelled reference number. Its two documented output types let you plan a JSON or Message connection, subject to inspecting the actual result.
When not to use Regex Extractor
Use JSON String Parser for a string containing a JSON object. Use Parser for template-based text extraction from structured input. For case changes, replacement or cleanup options, consider Text Operations. Pattern matching does not establish that a value is valid for a business rule.
Minimal configuration
example configuration, not a recorded test
| Catalogue input name | Example setting |
|---|---|
input_text | Reference: ABC |
pattern | ABC |
The pattern is a literal regular expression with no engine-specific syntax. It illustrates the two required settings without promising a match count, output object or captured-group format.
Limitations
- The catalogue lists only input_text and pattern. There is no exported setting for regex flags, a match limit or a timeout.
- Regex engine, capture-group handling, first-versus-all matching, invalid-pattern errors and no-match behavior are not supplied. Confirm them before a downstream step depends on a particular shape.
- An extracted string is not an authorization or schema-validation result. Review it against your intended rule before using it in a write or request.
