DOM Get parent XML element 


 

DOM Get parent XML element ( elementRef {; parentElemName {; parentElemValue}} ) -> Function result 
Parameter Type   Description
elementRef  String in XML element reference
parentElemName  String in Name of parent XML element
parentElemValue  String in Value of parent XML element
Function result  String in Parent XML element reference (16 characters)

The DOM Get parent XML element command returns an XML reference to the “parent” of the XML element passed as reference in elementRef. This reference may be used with the other XML parsing commands.

The optional parentElemName and parentElemValue parameters, when passed, receive respectively the name and value of the parent element.

When you pass a root element in elementRef, the command returns the "#document" reference. The document node is the parent of a root element.
If you use this command on a document node, the command returns a null reference ("0000000000000000") and the OK variable is set to 0.

If the command has been executed correctly, the system variable OK is set to 1. Otherwise, it is set to 0.
