read file xmlreader and writer xmlwriter after root node

[danimian]

Hello,
first i am creating xml file if file does not exist.

String myFile = "C:\myxmlfile.xml"; 
if (!File.Exists(myFile)) { 
using (FileStream conStream = new FileStream(myFile, FileMode.Create, FileAccess.Write)) { 
XmlWriter conWriter = new XmlTextWriter(conStream, Encoding.UTF8); 
conWriter.WriteStartDocument(); 
conWriter.WriteStartElement("myrootnode"); 
conWriter.WriteStartElement("myfirstnode"); 
conWriter.WriteEndDocument(); 
conWriter.Close(); 
conStream.Close(); 
} 
else 
{ 
 here read file which i just created in above code and write after new entries after root node, How to implement it or How to search for rootnode and attach new entries after root node? 
Any help would be highly appreciated. 
Thanks 
} 

Best Regards
Adnan

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

For working with XML files, I'd highly recommend the XmlDocument class, and accompanying XmlNode classes.

The thing to know is that XML in an XmlDocument object is set up as a hierarchical node structure... think a TreeView object. So once you read your XML text into the XmlDocument object, you can traverse through the ChildNodes recursively.

Play around with it and see what you can find out :)
