Description
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.
System variables and sets
If the command has been executed correctly, the system variable OK is set to 1. Otherwise, it is set to 0.
