Now there are various way you can update XML file -

• Update Single ParentNode
• Update attribute of a Node
• Add a new node under existing node
• Add new Attribute to the Node

Update Single ParentNode

Set TitleNode = oXMLFile.SelectSingleNode("/catalog/book[0]/title")

TitleNode.Text = "I am the new Title Here"

Update attribute of a Node

Set oAttribute = oXMLFile.SelectSingleNode("/catalog/book[0]/@id")

oAttribute.Text = "1111111111111111111111111111"

Add a new node under existing node

' select a parent node

Set ParentNode = oXMLFile.SelectSingleNode("/catalog/book[1]")

' add a new childNode

Set childNode = oXMLFile.CreateElement("NewNode")

childNode.Text = "I am The New NOde Here"

ParentNode.AppendChild (childNode)

Add new Attribute to the Node

'Add new Attribute to the Node

Set ParentNode = oXMLFile.SelectSingleNode("/catalog /book[2]/publish_date")

' add its attribute

Set newChildAttribute = oXMLFile.CreateAttribute("Status")

newChildAttribute.Text = "Very Old Book"

ParentNode.Attributes.SetNamedItem (newChildAttribute)

Complete Code:

Sub UpdateXML()
Call fnUpdateXMLByTags
End Sub

Function fnUpdateXMLByTags()
