Problem Statement

Create a function that takes a list of character names and a list of corresponding remarks and returns an XML document of elements each with a name attributes and each enclosing its remarks. All elements are to be enclosed in turn, in an outer element. As an example, calling the function with the three names of: And three remarks of: Should produce the XML (but not necessarily with the indentation): The document may include an declaration and document type declaration, but these are optional. If attempting this task by direct string manipulation, the implementation must include code to perform entity substitution for the characters that have entities defined in the XML 1.0 specification. Note: the example is chosen to show correct escaping of XML strings. Note too that although the task is written to take two lists of corresponding data, a single mapping/hash/dictionary of names to remarks is also acceptable. Note to editors: Program output with escaped characters will be viewed as the character on the page so you need to 'escape-the-escapes' to make the RC entry display what would be shown in a plain text viewer (See this). Alternately, output can be placed in tags without any special treatment.

Let's start with the solution:

$$ MODE TUSCRIPT
STRUCTURE xmloutput
DATA ''
DATA * '  ' remarks +''
DATA = ''
ENDSTRUCTURE
BUILD X_TABLE entitysubst=" >> > << < & & "
ERROR/STOP CREATE ("dest",seq-o,-std-)
ACCESS d: WRITE/ERASE/STRUCTURE  "dest" num,str
str="xmloutput"
  names=*
  DATA April
  DATA Tam O'Shanter
  DATA Emily
  remarks=*
  DATA Bubbly: I'm > Tam and <= Emily
  DATA Burns: "When chapman billies leave the street ..."
  DATA Short & shrift
  remarks=EXCHANGE(remarks,entitysubst)
WRITE/NEXT d
ENDACCESS d
