XSL Tranformation Action Block not working

HI All,

We have recently moved from MII12.1 to 15.1.

Some of our interfaces involved XSL transformation on the XML files and for some reasons, the XML transformation action block is not working.

We are getting error like

• [WARN] [XSL_Transformation_0]The result of XSLTransformation is not a valid XML

We tried different options of loading XML file, like creating a local XML variable and assigning that to InputXSL property, creating new file in web folder and assigning link to this file as input Transform Property but with no luck.

Same peace of code is working fine on MII 12.1, is this a bug in MII 15.1 or we are doing something wrong.

Thanks

Rupesh
