sethspace


Purpose
Set horizontal spacing of a node.
Synopsis
procedure sethspace(doc:xmldoc, n:integer, s:integer)
Arguments
doc 
Document to use
Node number
Number of spaces to put before the node output
Example
The following example reformats the XML document layout by adding an additional line before 'region' nodes and printing three consecutive tags within 'employee' on a single line. The indentmode is set to 'manual' in order to apply the user formatting (instead of automatic or none).
  declarations
    DB: xmldoc
    NodeList, Employees: list of integer
  end-declarations
  
! New line without indentation for Root
  setvspace(DB, Root, 1)

! Add extra line in between regions, keeping original indentation
  getnodes(DB, "personnelList/region", NodeList)
  forall(r in NodeList) setvspace(DB, r, 2)

! Spacing/indentation for 'employee' tag
  getnodes(DB, "personnelList/region/employee", Employees)
  forall(p in Employees) do
    setvspace(DB, p, 1); sethspace(DB, p, 4)

  ! Within 'employee', display up to 3 consecutive tags on a single line
    getnodes(DB, p, "child::node()[position() mod 3=1]", NodeList)
    forall(r in NodeList) do
      setvspace(DB, r, 1); sethspace(DB, r, 6)
    end-do  
    getnodes(DB, p, "child::node()[position() mod 3<>1]", NodeList)
    forall(r in NodeList) do
      setvspace(DB, r, 0); sethspace(DB, r, 1)
    end-do  
  end-do  

! Set indentation mode to 'manual' to use our own formatting for display
  setindentmode(DB, XML_MANUAL)
  save(DB, "") 
Further information
This spacing indicates the number of spaces to skip from the start of a new line before displaying the node when outputing the document. The horizontal spacing setting is only used when the indentation is in manual mode (see setindentmode).
