Fetch 3 XML outputs in Ado.net

Hi,

My SP output is 3 xml data sets (For which i m getting using XML Explicit)

which method i have to use to catch in ado.net?

(For single xml dataset i am using 

public  XmlDocument GetMenuXML()
            {
                System.Xml.XmlDocument doc = Db.ExecuteXMLReader("ABC_XML");
                return doc;
            }

which workes fine for me)

but with three how to deal ?
