Hi,
Do you mean the feature like this URL:
https://codebeautify.org/xml-xsl-transformation#
for transformation XML-XSLT?
Basically, DevTest does not include this kind of feature.
However, if you have code(or logic) about this type of transformation, you can realize same feature in DevTest by using the Execute Script (JSR-223) Step.
The Execute Script (JSR-223) Step supports scripts below:
•Applescript (for OS X)
•Beanshell
•Freemarker
•Groovy
•JavaScript
•Velocity
But you need to debug after write script in this step.
Cheers,
