Reading and updating an xml file

[jaleel]

Hi I havw an XML file in my windows application which is used to store some
project details. I want to read some node value from this file and then update one value of another node. Can anybody help me to do this...?

XML file looks like this:

[HTML]
<AFPDetails>

<Printer>
<AFPPrinter>IBM AFP 240</AFPPrinter> 'want to read this IBM AFP240 value
</Printer>

<FileName>
<NextNumber>0</NextNumber> want to update 0 to 1,2...
</FileName>
</AFPDetails>


[/HTML]


I am using a code like this :

        Dim xmlDocumnetObject As XmlDataDocument = New XmlDataDocument
        Dim xmlNodeObject As XmlNode
  xmlDocumnetObject.Load("AFPDetails.xml")
 
' to read value . This work fine
xmlNodeObject = xmlDocumnetObject.SelectSingleNode("//Printer/AFPPrinter")
 
        If Not xmlNodeObject Is Nothing Then
 
            AFPDriver = xmlNodeObject.InnerText
 
        End If
 
 
'write value .This has not updated in the xml file but no exception thrown
 
 
xmlNodeObject = xmlDocumnetObject.SelectSingleNode("//FileName/NextNumber")
            If xmlNodeObject IsNot Nothing Then
                xmlNodeObject.InnerText = (fileNextNumber + 1).ToString
 
                xmlDocumnetObject.Save("AFPDetails.xml")
            End If
 
 

thanks in advance

finally I got the problem and solved. In xmlDocumnetObject.Save("AFPDetails.xml") statement , we need to specify the correct path.

Thanks
