You can use XML types. Here is a sample procedure:

CREATE PROCEDURE udsp_VariableParams(@params XML)
AS
BEGIN
    DECLARE @vdoc INT
    EXEC sp_xml_preparedocument @vdoc OUTPUT, @params
    SELECT * FROM OPENXML(@vdoc, '/params/param', 1) WITH ([paramname] VARCHAR(40), [paramvalue] VARCHAR(150))
    EXEC sp_xml_removedocument @vdoc    
END

EXEC udsp_VariableParams 
  '
     
     
  '

EXEC udsp_VariableParams 
  '
     
     
     
  '
