C# 2010 working with xml

Question

I have been consuming (looking at) the results I see from a web service that I am going to obtain to call. As part of the process, I started a shell C# 2010 app that will look at the information obtained from the web service. I have been able to obtain the PDF documents by specifying where those files should be located in an app.config file.

However my problem is obtaining the results of an xml and an xsd file. The xml/xsd information is not  saved to any file. This information is displayed in a dos prompt window when I run a command script. I have been able to save the output to a text file by doing a redirection statement to write the information to a text file.

However I would like to know how I can capture the xsd/xml file so that I can parse through the information to extract the specific information I am looking for.

Thus, can you tell me and/or point me to a reference that will tell me how to accomplish this task?
