  • ProcessingInstruction represents an XML ProcessingInstruction node.

  • It includes methods to detach the node, get its raw data, retrieve its parent element, get its target, and get its text value.

  • Thedetach() method removes the node from its parent, returning the detached node.

  • ThegetData() method returns the raw data of the instructions within the node as a string.

  • ThegetParentElement() method returns the parent Element node or null if no parent exists.

  • ThegetTarget() method returns the target of the ProcessingInstruction node as a string.
