class SimpleType a where Source #

Ultimately, an XML parser will find some plain text as the content of a simpleType, which will need to be parsed. We use a TextParser, because values of simpleTypes can also be given elsewhere, e.g. as attribute values in an XSD definition, e.g. to restrict the permissible values of the simpleType. Such restrictions are therefore implemented as layered parsers.

class Extension t s where Source #

A type t can extend another type s by the addition of extra elements and/or attributes. s is therefore the supertype of t.

Methods

supertype :: t -> s Source #

class Restricts t s | t -> s where Source #

A type t can restrict another type s, that is, t admits fewer values than s, but all the values t does admit also belong to the type s.

Methods

restricts :: t -> s Source #

class FwdDecl fd a | fd -> a Source #

A trick to enable forward-declaration of a type that will be defined properly in another module, higher in the dependency graph. fd is a dummy type e.g. the empty data FwdA, where a is the proper data A, not yet available.

getAttribute :: (SimpleType a, Show a) => String -> Element Posn -> Posn -> XMLParser a Source #

Generated parsers will use getAttribute as a convenient wrapper to lift a SchemaAttribute parser into an XMLParser.

between :: PolyParse p => Occurs -> p a -> p [a] Source #

Between is a list parser that tries to ensure that any range specification (min and max elements) is obeyed when parsing.

data Occurs Source #

parseSimpleType :: SimpleType t => XMLParser t Source #

Given a TextParser for a SimpleType, make it into an XMLParser, i.e. consuming textual XML content as input rather than a String.

parseText :: XMLParser String Source #

Parse the textual part of mixed content

data AnyElement Source #

The xsd:any type. Parsing will always produce an UnconvertedANY.

Constructors

forall a.(SchemaType a, Show a) => ANYSchemaType a 
UnconvertedANY (Content Posn) 

data Content i Source #

Constructors

CElem (Element i) i 
CString Bool CharData i

bool is whether whitespace is significant

Instance details

Defined in Text.XML.HaXml.Verbatim

Methods

verbatim :: Content i -> String Source #

type XMLParser a = Parser (Content Posn) a Source #

We need a parsing monad for reading generic XML Content into specific datatypes. This is a specialisation of the Text.ParserCombinators.Poly ones, where the input token type is fixed as XML Content.

posnElement :: [String] -> XMLParser (Posn, Element Posn) Source #

A specialisation of posnElementWith (==).

posnElementWith :: (String -> String -> Bool) -> [String] -> XMLParser (Posn, Element Posn) Source #

Get the next content element, checking that it has one of the required tags, using the given matching function. (Skips over comments and whitespace, rejects text and refs. Also returns position of element.)

element :: [String] -> XMLParser (Element Posn) Source #

Get the next content element, checking that it has one of the required tags. (Skips over comments and whitespace, rejects text and refs.)

interior :: Element Posn -> XMLParser a -> XMLParser a Source #

Run an XMLParser on the contents of the given element (i.e. not on the current monadic content sequence), checking that the contents are exhausted, before returning the calculated value within the current parser context.

text :: XMLParser String Source #

text is a counterpart to element, parsing text content if it exists. Adjacent text and references are coalesced.

module Text.Parse

toXMLElement :: String -> [[Attribute]] -> [[Content ()]] -> [Content ()] Source #

addXMLAttributes :: [[Attribute]] -> [Content ()] -> [Content ()] Source #

For a ComplexType that is an extension of a SimpleType, it is necessary to convert the value to XML first, then add in the extra attributes that constitute the extension.
