'  Find the direct child node having the tag "meat", and

         & child.Content & vbCrLf

'  The same can be accomplished without creating a new
'  XML object instance.  Instead, the FindChild2 method updates
'  the caller's internal reference to the found child, if successful.

If (success = true) Then
    '  Success!  The xml object now references the found child.

    '  Restore the reference back to the parent.
