removeNamedItem()

Is a member of:

XML DOM NamedNodeMap

Syntax

set objXMLDOMNode = objXMLDOMNamedNodeMap.removeNamedItem(strAttribute)

Remark

Here we repeat our introduction to getNamedItem(). The XMLDOMNamedNodeMap object is used to find and manipulate attributes for a Node, although the XMLDOMElement interface gives you many methods as well to do this.

For all the remove type methods, the Node may be removed from the instantiated DOMDocument -but it is not yet removed from the actual XML file -until you have called the save() method

This method takes the name of an attribute to remove the attribute from an element Node. It is the similar to the removeAttribute() method, except that it returns the removed attribute, and it's a method for a different object.

Example

In the following example, we get a reference to an XMLDOMNamedNodeMap object, in order to use the removeNamedItem() method.

Dim objDOMDocument As DOMDocument

Dim objNamedNodeMap As IXMLDOMNamedNodeMap

Dim objAttrib As IXMLDOMAttribute

Set objDOMDocument = New DOMDocument

objDOMDocument.async = False

objDOMDocument.Load "http://localhost/xmlcode/people2.dtd"

Set objNamedNodeMap = objDOMDocument.documentElement.first-
Child.Attributes

Set objAttrib = objNamedNodeMap.removeNamedItem("PERSONID")

If objAttrib Is Nothing Then

' this removal was unsuccessful, show warning

End If

¬ This method can also be done in one line of code:

¬ Set objAttrib = objDOMDocument.documentElement.firstChild. Attributes.removeNamedItem("PERSONID")

¬ Get a reference to the XMLDOMNamedNodeMap object, which is returned from the attributes property.

¬ Remove the attribute using the attributes name.
