Table 2-23 Summary of ProcessingInstructionRef Methods; Dom Package

Function	Summary
ProcessingInstructionRef()	Constructor.
getData()	Get processing instruction's data.
getTarget()	Get processing instruction's target.
setData()	Set processing instruction's data.
~ProcessingInstructionRef()	Public default destructor.

ProcessingInstructionRef()

Class constructor.

Syntax	Description
ProcessingInstructionRef( const NodeRef< Node>& node_ref, Node* nptr);	Used to create references to a given `ProcessingInstruction` node after a call to create `ProcessingInstruction`.
ProcessingInstructionRef( const ProcessingInstructionRef< Node>& nref);	Copy constructor.

Parameter	Description
node_ref	reference to provide the context
nptr	referenced node

Returns

(ProcessingInstructionRef) Node reference object

getData()

Returns the content (data) of a processing instruction (in the data encoding). The content is the part from the first non-whitespace character after the target until the ending "?>".

Syntax

oratext* getData() const;

Returns

(oratext*) processing instruction's data

getTarget()

Returns a processing instruction's target string. The target is the first token following the markup that begins the ProcessingInstruction. All ProcessingInstructions must have a target, though the data part is optional.

Syntax

oratext* getTarget() const;

Returns

(oratext*) processing instruction's target

setData()

Sets processing instruction's data (content), which must be in the data encoding. It is not permitted to set the data to NULL. The new data is not verified, converted, or checked.

Syntax

void setData( 
   oratext* data) 
throw (DOMException);

Parameter	Description
data	new data

~ProcessingInstructionRef()

This is the default destructor.

Syntax

~ProcessingInstructionRef();
