var nodeBook, nodePublishDate;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
var myErr = xmlDoc.parseError;
WScript.Echo("You have error " + myErr.reason);
} else {
nodePublishDate = xmlDoc.createAttribute("PublishDate");
nodePublishDate.value = String(Date());
nodeBook = xmlDoc.selectSingleNode("//book");
nodeBook.attributes.setNamedItem(nodePublishDate);
WScript.Echo(nodeBook.getAttribute("PublishDate"));
}
Output

}
catch(...)
{
if(bstrAttributeName)
::SysFreeString(bstrAttributeName);
if(pIXMLDOMElement)
pIXMLDOMElement->Release();
if(pIXMLDOMNamedNodeMap)
pIXMLDOMNamedNodeMap->Release();
if(pIXMLDOMAttribute)
pIXMLDOMAttribute->Release();
if(pIXMLDOMNode)
pIXMLDOMNode->Release();
DisplayErrorToUser();
}
// Release pIXMLDOMDocument when finished with it.
Remarks
If an attribute already exists with the name in IXMLDOMNode
, the supplied replaces the existing attribute. The attribute name appears in its IXMLDOMNode
property.
If the newItem
node type is not NODE_ATTRIBUTE
, setNamedItem
returns an error. For example, it is not possible to modify entities or notations, which are read-only.
