The PLISAXB built-in subroutine allows you to invoke the XML parser for an XML document residing in a file.

Under batch, the character string specifying the input file should have the form 'file://dd:ddname', where ddname is the name of the DD statement specifying the file.
Under z/OS UNIX, the character string specifying the input file should have the form 'file://filename', where filenameis the name of a z/OS UNIX file.
Under both batch and z/OS UNIX, the character string specifying the input file should have no leading or trailing blanks.
The input XML file must be less than 2G in size. Moreover, since the parser will read the entire file into memory, the REGION for your program must be large enough for the parser to obtain a piece of storage that can contain all of the document.
