Synopsis

DTD structure

data DTD Source

A DTD is a sequence components in any order.

Constructors

DTD
Fields dtdTextDecl :: Maybe DTDTextDecl dtdComponents :: [DTDComponent]

Instances

Eq DTD
Show DTD
Typeable DTD

data DTDTextDecl Source

The ?xml text declaration at the beginning of a DTD.

Constructors

DTDTextDecl
Fields dtdXMLVersion :: Maybe Text dtdEncoding :: Text

Instances

Eq DTDTextDecl
Show DTDTextDecl
Typeable DTDTextDecl

data DTDComponent Source

The kinds of components that can appear in a DTD.

Constructors

DTDEntityDecl EntityDecl	Entity declaration
DTDElementDecl ElementDecl	Element declaration
DTDAttList AttList	List of attribute declarions for an element
DTDNotation Notation	A notation declaration
DTDInstruction Instruction	A processing instruction
DTDComment Text	A comment

Instances

Typeable DTDComponent

Entity declarations and references

data EntityDecl Source

Constructors

InternalGeneralEntityDecl
Fields entityDeclName :: Text entityDeclValue :: Text
ExternalGeneralEntityDecl	An external general entity is unparsed if a notation is specified.
Fields entityDeclName :: Text entityDeclID :: ExternalID entityDeclNotation :: Maybe Text

Instances

Eq EntityDecl
Show EntityDecl
Typeable EntityDecl

Element declarations

data ElementDecl Source

A declaration of an element.

Constructors

ElementDecl
Fields eltDeclName :: Text eltDeclContent :: ContentDecl

Instances

Eq ElementDecl
Show ElementDecl
Typeable ElementDecl

data ContentDecl Source

The content that can occur in an element.

Constructors

ContentEmpty	No content
ContentAny	Unrestricted content
ContentElement ContentModel	Structured element content
ContentMixed [Text]	A mixture of text and elements

Instances

Eq ContentDecl
Show ContentDecl
Typeable ContentDecl

data ContentModel Source

A model of structured content for an element.

Constructors

CMName Text Repeat	Element name
CMChoice [ContentModel] Repeat	Choice, delimited by `"\|"`
CMSeq [ContentModel] Repeat	Sequence, delimited by `","`

Instances

Eq ContentModel
Show ContentModel
Typeable ContentModel

data Repeat Source

The number of times a production of content model syntax can repeat.

Constructors

One
ZeroOrOne
ZeroOrMore
OneOrMore

Instances

Eq Repeat
Show Repeat
Typeable Repeat

Attribute declarations

data AttList Source

A list of attribute declarations for an element.

Constructors

AttList
Fields attListElementName :: Text The name of the element to which the attribute declarations apply attListDecls :: [AttDecl]

Instances

Eq AttList
Show AttList
Typeable AttList

data AttDecl Source

A declaration of an attribute that can occur in an element.

Constructors

AttDecl
Fields attDeclName :: Text The name of the attribute attDeclType :: AttType The type of the attribute attDeclDefault :: AttDefault The default value specification

Instances

Eq AttDecl
Show AttDecl

data AttType Source

The type of value that an attribute can take.

Constructors

AttStringType	Any text
AttIDType	A unique ID
AttIDRefType	A reference to an ID
AttIDRefsType	One or more references to IDs
AttEntityType	An unparsed external entity
AttEntitiesType	One or more unparsed external entities
AttNmTokenType	A name-like token
AttNmTokensType	One or more name-like tokens
AttEnumType [Text]	One of the given values
AttNotationType [Text]	Specified by external syntax declared as a notation

Instances

Eq AttType
Show AttType
Typeable AttType

data AttDefault Source

A default value specification for an attribute.

Constructors

AttRequired	No default value; the attribute must always be supplied
AttImplied	No default value; the attribute is optional
AttFixed Text	When supplied, the attribute must have the given value
AttDefaultValue Text	The attribute has the given default value when not supplied

Instances

Eq AttDefault
Show AttDefault
Typeable AttDefault

Notation declarations

data Notation Source

A declaration of a notation.

Constructors

Notation
Fields notationName :: Text notationSource :: NotationSource

Instances

Eq Notation
Show Notation
Typeable Notation

data NotationSource Source

A source for a notation. We do not use the usual ExternalID type here, because for notations it is only optional, not required, for a public ID to be accompanied also by a system ID.

Constructors

NotationSysID Text	A system ID
NotationPubID Text	A public ID
NotationPubSysID Text Text	A public ID with a system ID

Instances

Eq NotationSource
Show NotationSource
Typeable NotationSource
