specified Property

Indicates whether the node (usually an attribute) is explicitly specified or derived from a default value in the document type definition (DTD) or schema.

Script Syntax

boolValue = oXMLDOMNode.specified;

Example

The following script example creates an IXMLDOMNode from the specified item in an IXMLDOMNamedNodeMap. It then displays whether or not the attribute was specified in the element, rather than in a DTD or schema.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
var currNode;
var objNamedNodeMap;
var myNode;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
   var myErr = xmlDoc.parseError;
   WScript.Echo("You have error " + myErr.reason);
} else {
   currNode = xmlDoc.documentElement.childNodes.item(0);
   objNamedNodeMap = currNode.attributes;
   myNode = objNamedNodeMap.item(0);
   WScript.Echo(myNode.specified ? "true" : "false");
}

Visual Basic Syntax

boolValue = oXMLDOMNode.specified

C/C++ Syntax

HRESULT get_specified(  
    VARIANT_BOOL *isSpecified);

Parameters

isSpecified[out, retval]
True if the attribute is explicitly specified in the element; False if the attribute value comes from the DTD or schema.

C/C++ Return Values

S_OK
The value returned if successful.

E_INVALIDARG
The value returned if the isSpecified parameter is Null.

Remarks

Boolean. The property is read-only. Returns True if the attribute is explicitly specified in the element. Returns False if the attribute value comes from the DTD or schema.

This value depends on the value of the nodeType property.

NODE_ATTRIBUTE	Returns True if the attribute was specified directly on the element. Returns False for default attributes.
NODE_CDATA_SECTION NODE_COMMENT NODE_DOCUMENT NODE_DOCUMENT_FRAGMENT NODE_DOCUMENT_TYPE NODE_ELEMENT NODE_ENTITY NODE_ENTITY_REFERENCE NODE_NOTATION NODE_PROCESSING_INSTRUCTION NODE_TEXT	Returns True.
