Dim dbglvlnode As Xml.XmlNode = doc.SelectSingleNode(String.Format("Config/Scanner[DeviceID = {0}]/DebugLevel", XMLstuff.DeviceID))

1) Is there a way of doing this using a single XPath 1.0 expression?
2) Is there a way of passing in an array of elements into a single Invoke call of the custom XSLT Context Function class? I'm working in VB.Net but am happy with any C# examples anyone can share.
