Question

I have a XML file(web.config) and I need to edit the value attribute of each tag, depend of the key name…

this is an example of the XML file:

<appSettings>
  <add key="A1" value="Hi" />
  <add key="B1" value="Hello" />
</appSettings>

I mean, How can I change the value “hi” & “hello” using the key attribute(A1 & B1) ??

Thanks alot

try this code, it works fine:

XmlDocument doc = new XmlDocument();
doc.Load("Your.xml");
XmlNodeList elementList = doc.GetElementsByTagName("add");
for (int i = 0; i < elementList.Count; i++)
{
    if(elementList[i].Attributes["key"].Value == "A1")
       elementList[i].Attributes["value"].Value = "NewValue";
}
