Extracting A Single Element From A MASSIVE XML File

[Uiop]

I need to extract a single element (I believe that's the correct word) from a literally massive XML file. I havn't got it uncompressed yet, but I fully expect it to be at least 4GB. I need to write a program using VB.net that can extract a single node/element from the XML file in less than 8 seconds with a low memory footprint.

Is this possible? Any help would be very much appriciated.

Try the XmlTextReader class.

Represents a reader that provides fast, non-cached, forward-only access to XML data.
