Hi Oliver
The System.XML namespace defines XMLReader and XMLWriter classes. See http://msdn2.microsoft.com/en-us/lib...er(VS.80).aspx
XML is fundamentally just plain text with a bunch of tags, much like XML.
If you want, you can treat a .xml file just like a text file, opening it StreamReader and writing with StreamWriter, for example. If all you need is to extract a few key strings from a file, this works well and can be a bit faster if the document is large. I wouldn't generally try to write an xml file as a text file, though; I'd use something from System.XML to make sure the document structure doesn't get broken.
