Example

The following script example creates a new IXMLDOMProcessingInstruction object and displays its XML representation.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0");
var pi;
pi = xmlDoc.createProcessingInstruction("xml", "version=\"1.0\"");
alert(pi.xml);

Output (in a message box)

<?xml version="1.0"?>

Example

The following Microsoft® Visual Basic® example creates a new IXMLDOMProcessingInstruction object and displays its XML representation.

Dim xmlDoc As New Msxml2.DOMDocument50
Dim pi As IXMLDOMProcessingInstruction
Set pi = xmlDoc.createProcessingInstruction("xml", "version=""1.0""")
MsgBox pi.xml

Output (in a message box)

<?xml version="1.0"?>
