Trim String

The Trim String node is used to remove any leading and trailing whitespace characters from a string. Whitespace characters include spaces, tabs, and newlines that appear before the first non-whitespace character or after the last non-whitespace character in a string.

General

Field	Description	Required
Node name	Node Name	true
Variable Name	Variable name containing string which you want to trim	true

Example

Let's say you want to remove all the leading and trailing whitespaces in @wscos@ stored in $.variables.password.

1. Set Variable Name to $.variables.password.

It will convert the string in place and store in the same variable. If variable $.variables.password doesn't exist, it'll raise an error.

Returns

This node does not return any value, but stores the trimmed string in the same variable provided in <Variable Name> in the flow context.
