We don't do your homework for you - it is set to help you learn. How do I know this is homework? Because this time of year we get a flood of new members asking this question.

First - refer to your course work. If you can't any idea of how to start this assignment then you need to discuss this with your tutor.

Secondly - learn how to research. This ability is probably the most important thing you can pick up from education - how to find the information you need.

First of all, please read my comment to the question. Seems, you have to write custom method to split[^] company name and product name from pname node.

There's few ways to achieve that. You can use:
XDocument Class (System.Xml.Linq)[^]
XmlDocument Class (System.Xml)[^]
or XML Serialization[^]
to manipulate xml data.

For small portion of data, you can use Linq, see: .NET Language-Integrated Query for XML Data[^]
LINQ - Sample Queries in C#, VB.NET for Visual Studio 2010[^]
In any other case, i'd suggest to use serialization and deserialization.
