The <transform> step has the following attributes:
input – An optional attribute that is the generalized path of the file on the target host on which to apply the transformation. If this attribute is omitted, input is read from the output file. This attribute can reference simple substitution variables.
output – A required attribute that is the generalized path of the file on the target host to which to write the result of the transformation. This attribute can reference simple substitution variables.
The input and output attributes can reference the same or distinct files. The value of these attributes is a generalized path that can include zip archives or zip derivatives, such as JAR, as directory elements. For example, a path might be webapp/myapp.jar/config.xml.
