createProcessingInstruction Method

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

objXMLDOMProcessingInstruction =
    oXMLDOMDocument.createProcessingInstruction(target, data)

Parameters

target

String specifying the target part of the processing instruction. This supplies the nodeName property of the new object.

data

String specifying the rest of the processing instruction preceding the closing ?> characters. This supplies the nodeValue property for the new object.

Return Value

Object. Returns the new XMLDOMProcessingInstruction object.

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. You must explicitly call one of the node insert methods—insertBefore, replaceChild, or appendChild—to add the new object.

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

Example

For example, to generate the processing instruction <?XML version="1.0"?>, specify the target string XML and the data string version="1.0":

Dim xmlDoc
Dim pi
Set xmlDoc = CreateObject("Msxml2.DOMDocument")
xmlDoc.async = False
xmlDoc.load("c:\books.xml")
Set pi = xmlDoc.createProcessingInstruction("xml", "version=""1.0""")
xmlDoc.insertBefore pi, xmlDoc.childNodes.item(0)
MsgBox (xmldoc.xml)
