Node
String data
The content of the processing instruction (i.e., the first non-space character after the target up to but not including the closing ?>).
readonly String target
The target of the processing instruction. This is the first identifier that follows the opening <?; it specifies the "processor" for which the processing instruction is intended.
This infrequently used interface represents a processing instruction (or PI) in an XML document. Programmers working with HTML documents will never encounter a ProcessingInstruction node.
