createProcessingInstruction Method

  • 项目

Creates a processing instruction node that contains the supplied target and data.

var objXMLDOMProcessingInstruction = oXMLDOMDocument.createProcessingInstruction(target, data);

HRESULT createProcessingInstruction(
  BSTR target,
  BSTR data,
  IXMLDOMProcessingInstruction** pi
);

General Remarks

Creating a processing instruction node with this method is the same as using createNode where the type parameter value is NODE_PROCESSING_INSTRUCTION and no namespace is specified. You cannot specify a namespace with the createProcessingInstruction method.

Although this method creates the new object in the context of this document, it does not automatically add the new object to the document tree. In other words, although the ownerDocument property of the new node points to this document object, the parentNode property is set to Null. To add the new object, you must explicitly call one of the node insert methods, insertBefore method, replaceChild method, or appendChild method.

The new object's nodeType property has the value NODE_PROCESSING_INSTRUCTION.

This method applies to the following objects and interfaces:

DOMDocument and IXMLDOMProcessingInstruction.
