XML Filtering for WebApp using Visual Studio

Asked by shawnsouthern in Microsoft Visual Basic.Net, .NET, Visual Studio 2008

Tags: Microsoft, VIsual Studio, 2008, VB

I am working on a WebApp in Visual Studio 2008, that will pull information from an XML file and display the information(date, time, temperatue and humidity). I am using a Datalist control to bind that data, using an XPath expression. The problem I am having is that when run I have empty nodes returned, I would like to filter the data to only return the current information (from the past hour). The problem is that the XML file is pulled from Environment Canada and some of the nodes have the same names so I can't seem to find a way to filter them properly. I have included my code, sample of output and the XML file I am drawing from.
