Description
The DOM Get previous sibling XML element command returns a reference to the previous “sibling” of the XML element passed as reference. This reference may be used with the other XML parsing commands.
The optional siblingElemName and siblingElemValue parameters, when passed, receive respectively the name and value of the previous “sibling” element.
This command can be used to navigate among the “children” of an XML element.
Before the first “sibling,” the system variable OK is set to 0.
System variables and sets
If the command has been executed correctly and if the referenced element is not the first “child” of the structure, the system variable OK is set to 1. If an error occurs or if the element parsed is the first “child” of the structure, it is set to 0.
