problem with xml

[Guest]

Hi,
I'm trying to get xml working, but even when I copy/paste a simple example
from online, I get the error

An unhandled exception of type 'System.Xml.XmlException' occurred in
system.xml.dll
Additional information: System error.

Here is the code I used:

string filename = @"C:\Catalog2.xml";
XmlDocument xml = new XmlDocument();
xml.Load(filename);

XmlNode root = xml.DocumentElement; <- Here's where problem begins
XmlElement childNode = xml.CreateElement("childNode");
XmlElement childNode2 = xml.CreateElement("SecondChildNode");
XmlText textNode = xml.CreateTextNode("hello");
textNode.Value = "hello, world";

root.AppendChild(childNode);
childNode.AppendChild(childNode2);
childNode2.SetAttribute("Name", "Value");
childNode2.AppendChild(textNode);

textNode.Value = "replacing hello world";
xml.Save(filename);

I'm sure it's something simple that I'm missing, but it's driving me crazy.
Thanks for any help!

Hi Melanieab,
it could be something to do with the contents of your XML file. What is
the XML inside the Catalog2.xml file?

Thanks
