You have a situation in which an external source supplies an XSLT file to perform the transformation, and you want to leverage the file. Which…

The Transform XML activity is specifically designed to apply an Extensible Stylesheet Language Transformation (XSLT) to an input XML document. Its configuration includes a field to specify the path to an external XSLT stylesheet file (.xsl or .xslt). This allows developers to leverage pre-existing or externally supplied transformation logic without embedding it directly into the process, which perfectly matches the requirement of using an XSLT file from an external source.

A. Mapper: The Mapper activity is used for visual data mapping using XPath within the IDE; it does not directly consume an external XSLT file for its transformation logic.

B. Render XML: This activity serializes a schema-based XML data structure into a text string. It is for data representation, not for applying XSLT transformations.

C. Invoke XSLT: This is not a valid or standard activity name within the TIBCO BusinessWorks palettes.

Quote: "The Transform XML activity is used to transform an input XML document into the desired output format by applying an XSLT transformation." The configuration section on the same page details the "Stylesheet" field where the path to the XSLT file is provided.

Quote: "The Render XML activity takes data that is structured based on an XML schema and renders it as a stream of bytes or a string." This confirms it does not perform XSLT transformations.
