Beginners Question...

[Peter Treier]

I got a XML file like this:

<?xml version="1.0" encoding="utf-16"?>
<LicenceControlFile>
<Licence1>2AB7-FA43-B05C-4C2A-8DBD</Licence1>
<MachineName />
<Licence2>2AB7-FA43-B05C-4C2A-8DBD</Licence2>
<MachineName />
<Licence3>2AB7-FA43-B05C-4C2A-8DBD</Licence3>
<MachineName />
</LicenceControlFile>

Now i need to set the Value of one of the <MachineName /> Elements !
How can i do this with .NET...

Thanks

Peter

The simplest (but not necessarily the most effective) way is to load document
to XmlDocument, select appropriate MachineName element using SelectSingleNode
method, update it and save document back.

Good evening Oleg

I've tried to do that, but i got one Error

<---Error

An unhandled exception of type 'System.InvalidOperationException' occurred
in system.xml.dll

Additional information: Cannot set a value on node type: Element.

--->End Error

I've selected the first Element with Xpath
loDoc is a XMLDocument

loDoc.SelectSingleNode("/LicenceControlFile/MachineName").Value =
sMachineName

Whats wrong ?

Forgot to mention, you have to create text node. In DOM elements have no
value. Text is stored in text nodes' value. So you have to create text node,
set its value and append it as a child to the element.
Something like
XmlNode elem = loDoc.SelectSingleNode("/LicenceControlFile/MachineName");
XmlText textNode = loDoc.CreateTextNode(sMachineName);
elem.AppendChild(textNode);
