How to edit a value of an element in an XML document ?

[Rob]

First of all, I am using VB.net within the compact framework for programing
a PDA...

I am trying to modify the value of an item in an xml document...

The only samples I see use the doc.SelectNodes method. When I try using
this I get an error stating that "SelectNode s" is not a member of
'System.Xml.Xml Document'.

Can anyone post a sample of how you would change the value of an item in an
xml document (using only the subset of methods allowed by the compact
framework, if possible) ?

Or maybe just another way other than using "select nodes"

thanks !

According to the documentation the method GetElementsByTa gName is
supported in the .NET compact framework. The InnerText property is also
supported.
If you show us the structure of the XML you want to manipulate then we
can probably show you a code snippet to use.

Hi Martin,

Yes, you are correct regarding ....

GetElementsByT agName is supported in the .NET compact framework. The
InnerText property is also supported.
However, "SelectNode s" does not appear to be supported..... which was the
method I sought to use.

I simply want to be able to change the value of the Delivered Tag to Yes.

<?xml version="1.0" encoding="UTF-8" ?>
- <AllOrders>
- <Order OrderId="123456 ">
<Route>1</Route>
<SalesOrder>123 456</SalesOrder>
<Customer>ABC </Customer>
<CustomerName>A lpha Company</CustomerName>
<ReqDeliveryDat e>5/27/2006</ReqDeliveryDate >
<Delivered>No </Delivered>
<Signed>No</Signed>
</Order>
- <Order OrderId="567890 ">
<Route>1</Route>

Thanks,
Rob

Thanks Martin...

Is this easily converted to vb.net ?

Also, how would you specify only for SalesOrder number 123456 ?

Thanks !

Here is a VB.NET example

Dim document As XmlDocument = New XmlDocument
document.Load(" file.xml")
For Each Order As XmlElement In
document.GetEle mentsByTagName( "Order")
Dim SalesOrder As XmlElement =
Order.GetElemen tsByTagName("Sa lesOrder")(0)
If Not SalesOrder Is Nothing And SalesOrder.Inne rText =
"123456" Then
Dim Delivered As XmlElement =
Order.GetElemen tsByTagName("De livered")(0)
If Not Delivered Is Nothing Then
Delivered.Inner Text = "Yes"
Exit For
End If
End If
Next
' save result, in this example to the console
' in reality to some file
document.Save(C onsole.Out)
