Comments

The script function identifies the last sub-element of an element in an XML document.

A handle must be given to the script function so that it can access the appropriate last sub-element. This reference specifies the position in the XML document. The very first handle is the one which is returned by XML_OPEN. It refers e.g. to the root element Content of the structured documentation.

XML_GET_LAST_CHILD switches a level deeper into the structure starting at the specified element. XML_GET_NEXTSIBLING retrieves the subsequent element on the same level.

Example

The following example determines the name of the last sub-element Info with the main element "Content" being the starting point.

:SET &XMLDOCU# = XML_OPEN(DOCU,"ON_CALL","@Details")

:SET &HND# = XML_GET_LAST_CHILD(&XMLDOCU#)

:   IF &HND# <> ""
:      SET &NAME# = XML_GET_NODE_NAME(&HND#)
:      PRINT "Last sub-element: &NAME#"
:   ELSE
:      PRINT "No sub-element"
:   ENDIF
