IXMLDOMElement.setAttribute (Visual Basic .NET)

The setAttribute method sets the value of the named attribute.

Syntax

  IXMLDOMElement
  .setAttribute(
  strName As String,
  varValue As Variant
)

Parameters

strName

[in] String specifying the name of the attribute. If the attribute with that name already exists, its value is changed. If the attribute with that name does not exist, it is created.

varValue

[in] Variant that supplies the value for the named attribute.

Remarks

If an attribute with the supplied name already exists, this method changes that attribute's value to the value supplied in the varValue parameter. The supplied name is not parsed, so any markup, such as syntax meant to be recognized as an entity reference, is treated as literal text and must be appropriately escaped by the implementation when it is written out.

Example Code

The following example sets the name and value of a new attribute for the specified element node.

Imports interop_msxml
Imports Microsoft.WindowsMediaServices.Interop

On Error GoTo Err

' Declare variables.
Dim Server As New WMSServerClass()
Dim Playlist As IXMLDOMDocument
Dim ElemList As IXMLDOMNodeList
Dim Elem As IXMLDOMElement
Dim Node As IXMLDOMNode

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

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

' Retrieve a list of nodes that matches the query.
ElemList = Playlist.getElementsByTagName("media")

' Retrieve the first node in the list.
Node = ElemList.item(0)

' Convert the first node into an IXMLDOMElement object.
Elem = CType(Node, IXMLDOMElement)

' Set the value for the attribute named "src".
Elem.setAttribute("src", "new_content.asf")
Exit Sub
