Create the import control file to import the XML

Create the import control file to import the XML

I am new in informatica, I just want to import the XML. To do this stuff I
have below command
pmrep objectimport -i ${XML_DIR}/${xml_file} -c ${CFN_DIR}/${cfn_file} -l
${PMLogDir}/${log_import_file}
But I haven't any idea to create the CFN file (import control file).
Can anyone help me on this.
