Task Purpose
The match task is used to find Regex (regular expression) matches in a string and returns the matches as an array.
Properties
Input and output parameters are shown below.
| Incoming | Type | Description |
|---|---|---|
str |
String | Required. The string to search. |
regExp |
String | Required. The regular expression to match. |
flags |
String | Indicates the flags to include. For a list of available flags, refer to the Regular Expressions guide on the MDN docs site. |
| Outgoing | Type | Description |
|---|---|---|
matches |
Array | Returns an array of the match results. If the regular expression does not include the g flag (to perform a Global Search), the task will return only the first match in the string. If no match is found, then 'null' is returned. |
How to Configure
In this example the str Reference variable to search are the words Hello World.
The regExp expression to match is the character /o/, and the flags variable is set to g, which is a Global Search of the entire string.
