D EmpInfo        DS                   QUALIFIED

 // <EMPNAME><Frstname>Scott</Frstname><LastName>Sherbert</LastName></EMPNAME>
 // <MNANE Frstname="Ken" LastName="Mahajan"></MNAME>
 //</empinfo>

    xml-into empInfo %XML('Employee.xml' : 'doc=file');
 // EMPInfo.EMPNme.Frstname='Scott' EMPInfo.EMPNme.Lastname = 'Sherbert'
 // EMPInfo.MName.Frstname='KenEMPInfo.MName.Lastname = 'Mahajan'

 // Parse the "empinfo/Mname/Lastname" information into variable
 // "MLName".  Use the "path" option to specify the location
 // of this information in the XML document.
