Creates an XML converter for repetitions of sequences represented as an XML element that can be used in repetitions.

Example call:
(eRepSeq4 name cons conv)
Parameters:
  • name : Tag name of the element
  • cons : constructor of the sequence
  • conv : (s) XML converter for the components
Returns:
XML element converter for a repeated sequence

seq5 :: (Data a, Data b, Data c, Data d, Data e, Data f) => (a -> b -> c -> d -> e -> f) -> XmlConv g h a -> XmlConv i j b -> XmlConv k l c -> XmlConv m n d -> XmlConv o p e -> XmlConv NotRepeatable NoElem f  Non-deterministic 

Creates an XML converter representing a sequence of arbitrary XML data. The sequence must not be used in repetitions and does not represent an XML element.

Example call:
(seq5 f conv)
Parameters:
  • f : Invertable function (constructor) that combines the sequence
  • conv : (s) XML converter for the data contained in the sequence
Returns:
XML converter representing a sequence

repSeq5 :: (Data a, Data b, Data c, Data d, Data e, Data f) => (a -> b -> c -> d -> e -> f) -> XmlConv Repeatable g a -> XmlConv Repeatable h b -> XmlConv Repeatable i c -> XmlConv Repeatable j d -> XmlConv Repeatable k e -> XmlConv NotRepeatable NoElem [f]  Non-deterministic 

Creates an XML converter that represents a repetition of a sequence of repeatable XML data. The repetition may be used in other repetitions and does not represent an XML element. This combinator is provided because converters for repeatable sequences cannot be constructed by the seq combinators.

Example call:
(repSeq5 f conv)
Parameters:
  • f : Invertable function (constructor) that combines the sequence
  • conv : (s) XML converter for the data contained in the sequence
Returns:
XML converter representing a repetition of a sequence

eSeq5 :: (Data a, Data b, Data c, Data d, Data e, Data f) => String -> (a -> b -> c -> d -> e -> f) -> XmlConv g h a -> XmlConv i j b -> XmlConv k l c -> XmlConv m n d -> XmlConv o p e -> XmlConv Repeatable Elem f  Non-deterministic 

Creates an XML converter for compound values represented as an XML element with children that correspond to the values components. The element can be used in repetitions.

Example call:
(eSeq5 name cons conv)
Parameters:
  • name : Tag name of the element
  • cons : constructor of the compound value
  • conv : (s) XML converter for the components
Returns:
XML element converter for a compound value

eRepSeq5 :: (Data a, Data b, Data c, Data d, Data e, Data f) => String -> (a -> b -> c -> d -> e -> f) -> XmlConv Repeatable g a -> XmlConv Repeatable h b -> XmlConv Repeatable i c -> XmlConv Repeatable j d -> XmlConv Repeatable k e -> XmlConv Repeatable Elem [f]  Non-deterministic 

Creates an XML converter for repetitions of sequences represented as an XML element that can be used in repetitions.

Example call:
(eRepSeq5 name cons conv)
Parameters:
  • name : Tag name of the element
  • cons : constructor of the sequence
  • conv : (s) XML converter for the components
Returns:
XML element converter for a repeated sequence

seq6 :: (Data a, Data b, Data c, Data d, Data e, Data f, Data g) => (a -> b -> c -> d -> e -> f -> g) -> XmlConv h i a -> XmlConv j k b -> XmlConv l m c -> XmlConv n o d -> XmlConv p q e -> XmlConv r s f -> XmlConv NotRepeatable NoElem g  Non-deterministic 

Creates an XML converter representing a sequence of arbitrary XML data. The sequence must not be used in repetitions and does not represent an XML element.

Example call:
(seq6 f conv)
Parameters:
  • f : Invertable function (constructor) that combines the sequence
  • conv : (s) XML converter for the data contained in the sequence
Returns:
XML converter representing a sequence

repSeq6 :: (Data a, Data b, Data c, Data d, Data e, Data f, Data g) => (a -> b -> c -> d -> e -> f -> g) -> XmlConv Repeatable h a -> XmlConv Repeatable i b -> XmlConv Repeatable j c -> XmlConv Repeatable k d -> XmlConv Repeatable l e -> XmlConv Repeatable m f -> XmlConv NotRepeatable NoElem [g]  Non-deterministic 

Creates an XML converter that represents a repetition of a sequence of repeatable XML data. The repetition may be used in other repetitions and does not represent an XML element. This combinator is provided because converters for repeatable sequences cannot be constructed by the seq combinators.

Example call:
(repSeq6 f conv)
Parameters:
  • f : Invertable function (constructor) that combines the sequence
  • conv : (s) XML converter for the data contained in the sequence
Returns:
XML converter representing a repetition of a sequence

eSeq6 :: (Data a, Data b, Data c, Data d, Data e, Data f, Data g) => String -> (a -> b -> c -> d -> e -> f -> g) -> XmlConv h i a -> XmlConv j k b -> XmlConv l m c -> XmlConv n o d -> XmlConv p q e -> XmlConv r s f -> XmlConv Repeatable Elem g  Non-deterministic 

Creates an XML converter for compound values represented as an XML element with children that correspond to the values components. The element can be used in repetitions.

Example call:
(eSeq6 name cons conv)
Parameters:
  • name : Tag name of the element
  • cons : constructor of the compound value
  • conv : (s) XML converter for the components
Returns:
XML element converter for a compound value

Parameters:
  • name : Tag name of the element
  • cons : constructor of the sequence
  • conv : (s) XML converter for the components
Returns:
XML element converter for a repeated sequence
