    I have the following XML file which I need to edit
    - <ImportSession DeleteBatchOnError="1">
    - <Batches>
    - <Batch BatchClassName="EmailOutput">
    - <Documents>
    - <Document RequestID="22">
    - <IndexFields>
      <IndexField Name="EmailFrom" Value="hello" /> 
      <IndexField Name="EmailFromAddress" Value="he.llo@hotmail.com" /> 
      <IndexField Name="EmailTo" Value="hello@hotmail.com" /> 
      <IndexField Name="EmailSubject" Value="Test Thursday" /> 
      <IndexField Name="EmailCC" Value="" /> 
      <IndexField Name="EmailDateTime" Value="9/25/2008 2:17:45 PM" /> 
      <IndexField Name="MailboxName" Value="mailbox" /> 
      <IndexField Name="OBJECT_CLASS" Value="Email" /> 
      <IndexField Name="Policy_No" Value="012344" /> 
      <IndexField Name="Claim_No" Value="999999999" /> 
      <IndexField Name="Broker_No" Value="876543" /> 
      </IndexFields>
      </Document>
      </Documents>
      </Batch>
      </Batches>
      </ImportSession>
    
    

    I can retrieve the values using the following
    Dim xmlObj As New Xml.XmlDocument
            Dim m_node As Xml.XmlNode
            Dim m_nodelist As XmlNodeList
            Dim policyNo as string
    
            xmlObj.Load(_file)
    
            m_nodelist = xmlObj.SelectNodes("/ImportSession/Batches/Batch/Documents/Document/IndexFields/IndexField[@Name='Policy_No']")
    
            'Load the document 
            Try
                m_nodelist = xmlObj.SelectNodes("/ImportSession/Batches/Batch/Documents/Document/IndexFields/IndexField[@Name='Policy_No']")
                For Each m_node In m_nodelist
                   policyNo = m_node.Attributes.GetNamedItem("Value").Value = "01PMV0123456"
                Next
    
    

    I need to edit the Policy_No element. Can some direct me in the right direction please.

    I tried doing setnameditem but looking for xml object
    Thanks in advance
