Importing
an XML document is the process of reading an external XML document
as a SAS data set. The XML engine translates the input XML document
to the SAS proprietary file format.
To import an XML document,
you execute the LIBNAME statement for the XML engine in order to assign
a libref to the physical location of an existing XML document. Then,
you execute SAS code to access the XML document as a SAS data set.
