IXMLDOMNamedNodeMap.setNamedItem (Visual Basic .NET)

The setNamedItem method adds the supplied node to the collection.

Syntax

  IXMLDOMNode = IXMLDOMNamedNodeMap
  .setNamedItem(
  newItem As IXMLDOMNode
)

Parameters

newItem

[in] IXMLDOMNode object containing the attribute to be added to the collection.

Return Values

Returns the attribute added to the collection.

Remarks

If the attribute to be added to the collection has the same name as an existing attribute, the supplied attribute replaces the existing attribute. The attribute name appears in the IXMLDOMNode.nodeName 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 because they are read-only.

Example Code

The following example creates a new attribute and adds it to the element node using the setNamedItem method.

Imports interop_msxml
Imports Microsoft.WindowsMediaServices.Interop

' Declare variables.
Dim Server As New WMSServerClass()
Dim Playlist As IXMLDOMDocument
Dim Elem As IXMLDOMElement
Dim ChildList As IXMLDOMNodeList
Dim XMLNamedNodeMap As IXMLDOMNamedNodeMap
Dim NodeMedia As IXMLDOMAttribute

' Create a new playlist object.
Set Playlist = Server.CreatePlaylist

' Load a playlist.
Playlist.Load ("file://c:\wmpub\wmroot\simple.wsx")

' Retrieve a pointer to the root element.
Elem = Playlist.documentElement

' Retrieve a list of the child nodes.
ChildList = Elem.childNodes

' Retrieve the list of attributes for the first
' node in the child node list.
XMLNamedNodeMap = ChildList.item(0).attributes

' Create a new attribute.
NodeMedia = Playlist.createAttribute("src")

' Set the value of the new attribute.
NodeMedia.value = "new_content.asf"

' Add the src attribute to the media element.
XMLNamedNodeMap.setNamedItem(NodeMedia)
Exit Sub
