transform Element child elements

The <transform> element children specify the transformation to be applied to the input file. The child elements can be any one of the following:

• A single <stylesheet> element defining an XSLT transform to apply on the input source.

• One or more <subst> elements defining Perl5-based substitution patterns to apply sequentially on the input source.

• A single <source> element naming an external file that contains the transform.

• Empty, meaning the content of the input file is copied directly to the output file. This is useful for extracting from or writing to zip archives.
