The other thing to look at is how are you serializing the infoset? The default XmlDocument.Save method will format the xml using indenting. You can change the behavior by setting the Formatting property of the XmlTextWriter to None.

...
XmlTextWriter xw = new XmlTextWriter(Console.Out); //substitute the name of your file here
xw.Formatting = Formatting.None;
oXml.Save(xw);
