Hi

See XmlDocument and XmlNode

You have to load document
XmlDocument dom = new XmlDocument ();
dom.Load ("...");
// then select node
XmlNode node = dom.SelectSingleNode("...");
node.attributes["address"].Value = "world";
// and then you could save
dom.Save(...);

Thanks. I have that but now I cannot get the file to close. I need the
file to save, but apparently even thought the Document object goes out of
scope a HANDLE to the file is still open. ???

If you are using XmlTextWriter, make sure you call Close() at the end.

Yeah, I found it. I have an MMC snap-in that modifies web.config on the fly
and when I got done showing it, well I forgot to close it. Ooops

know that you implement some code to change your web.config file. I'm trying
to do the same.
I can change it successfully, but then when I check my config file using
"ConfigSettings", he gaves back to me the old values



Seems to me that the application loads the file into memory and then, if I
want I have to reload the config file.

Can you tell me how to do this?

Here's a sample. Place your names in as needed:

public void ModifyAttribute(string strXPath, string strKey, string strNewValue)
{
try
{
XmlDocument doc = new XmlDocument();
doc.Load(@"c:\adbs\bin\web.config");
XmlNodeList nodeList = doc.SelectNodes(strXPath);
foreach (XmlNode node in nodeList)
{
string strValue = node.Name;
if(node.Attributes["key"].Value == strKey)
{
node.Attributes["value"].Value = strNewValue;
}
}
doc.Save(@"c:\adbs\bin\web.config");
}
catch(Exception ex)
{
throw ex;
}
}
public void ModifyAllAttributes(string strXPath, string strAttribute, string
strNewValue)
{
try
{
XmlDocument doc = new XmlDocument();
doc.Load(@"c:\adbs\bin\web.config");
XmlNodeList nodeList = doc.SelectNodes("//ADBSSectionGroup//ADBSSoapTracing//add");
foreach (XmlNode node in nodeList)
{
node.Attributes["value"].Value = strNewValue;
}
doc.Save(@"c:\adbs\bin\web.config");
}
catch(Exception ex)
{
throw ex;
}
}
