STRING MATCHES WITH¶
Checks whether a needle string (treated as a regex pattern) exists within a haystack string and returns the match result. Use this worker whenever a workflow needs a simple string-search or pattern-match decision step.
When to use¶
Classification: process.
Tagged: match, pattern, regex, scalar, search, string, transformation.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Haystack | haystack | scalar | — | ✓ | The source string to search within; provide any plain-text or serialized scalar value that should be inspected for the pattern. |
| Needle | needle | scalar | — | ✓ | The pattern (interpreted as a regex) to search for inside the haystack; e.g. ‘error’ or ‘[0-9]+’ — no surrounding slashes needed, they are added automatically. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| string_match_output_1 | string_match_output_1 | scalar | The result of the regex match operation — typically the matched substring or a truthy/falsy scalar indicating whether the needle pattern was found in the haystack. |
