// Get ( [resource requesting the query], [setting name], [return buffer], [return buffer length], [delete node] )
//
// bDeleteNode contains a boolean to indicate whether the table contains one entry or multiple entries. If multiple
// entries are used, the resource's storage node (which only gets deleted on resource stop) is used to store any
// matching nodes that you have access to. The boolean is meant to let the caller know that the XML node that is
// returned should be deleted after usage, for the sake of memory usage.
//
// Returns the XML node.
//
// If ( bDeleteNode == TRUE ), always remove the XML node after you're done with it!
