    new XAttribute("Att1", "content1"),  
    new XAttribute("Att2", "content2"),  
    new XAttribute("Att3", "content3")  
);  
XAttribute att = root.Attribute("Att2");  
att.SetValue("new content");  
Console.WriteLine(root);  

Dim root As XElement = <Root Att1="content1" Att2="content2" Att3="content3"/>  
Dim att As XAttribute = root.Attribute("Att2")  
att.SetValue("new content")  
Console.WriteLine(root)  

This example produces the following output:

<Root Att1="content1" Att2="new content" Att3="content3" />  

Remarks
