DOM Get last child XML element 


 

DOM Get last child XML element ( elementRef {; childElemName {; childElemValue}} ) -> Function result 
Parameter Type   Description
elementRef  String in XML element reference
childElemName  String in Name of child element
childElemValue  String in Value of child element
Function result  String in XML element reference

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

The optional childElemName and childElemValue parameters, when passed, receive respectively the name and value of the “child” element.

Example  

Recovery of the reference of the last XML element of the parent root. The XML structure (C:\\import.xml) is loaded into a BLOB beforehand:

 C_BLOB(myBlobVar)
 C_TEXT($ref_XML_Parent;$ref_XML_Child)
 C_TEXT($childName;$childValue)
 
 DOCUMENT TO BLOB("c:\\import.xml";myBlobVar)
 $ref_XML_Parent:=DOM Parse XML variable(myBlobVar)
 $ref_XML_Child:=DOM Get last child XML element($ref_XML_Parent;$childName;$childValue)

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