Purpose
Get the successor of a node.
Synopsis
function getnext(doc:xmldoc, n:integer):integer
Arguments
doc

n 
Node number
Return value
The node number of the following node or -1 if the current node is the last of the list.
Example
This example enumerates all child nodes within a specific region and displays the 'id' for all 'employee' nodes on a single line, adding a line break after the last name: 
  declarations
    DB: xmldoc
    APAC, Pers: integer
  end-declarations

  APAC:= getnode(DB, "personnelList/region[@id='APAC']")
  Pers:= getfirstchild(DB, APAC)
  LastPers:= getlastchild(DB, APAC)
  while(Pers>-1) do
    if getname(DB, Pers)="employee" then
      write(" ", getattr(DB,Pers,"id"))
    end-if
    if Pers=LastPers then writeln; end-if
    Pers:= getnext(DB, Pers)
  end-do
Further information
Node numbers returned by Mosel are not directly related to the order of nodes within the XML document ( i.e. a larger node number does not imply that a node succeeds a node with a smaller number).
