Parse Template Reference in Mule4

Overviews

The Parse Template component loads a file into the Mule payload. The ‘Parse Template’ transformer parses a template file that can contain Mule Expression Language and places the resulting string into the message payload. Use a parse template to load the content of a flow-external file into a Mule flow, then use the file as a template into which you can insert data returned as the result of evaluated Mule expressions.

Parse Template

Parse Template is the Mule component to use for processing a template and obtaining a result. A template is defined as text with embedded Mule expressions that are evaluated and replaced with their result.
