HaXml-1.25.7: Utilities for manipulating XML documents
Safe HaskellSafe-Inferred




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

We need a Parser monad for reading from a sequence of generic XML Contents into specific datatypes that model the structure of XSD descriptions. This is a specialisation of the polyparse combinators, fixing the input token type.

(|||) :: (a -> Bool) -> (a -> Bool) -> a -> Bool Source #

Lift boolean or over predicates.

xsd :: Name -> QName Source #

Qualify an ordinary name with the XSD namespace.

xsdTag :: String -> Content Posn -> Bool Source #

Predicate for comparing against an XSD-qualified name. (Also accepts unqualified names, but this is probably a bit too lax. Doing it right would require checking to see whether the current schema module's default namespace is XSD or not.)

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

Get the next content element, checking that it matches some criterion given by the predicate. (Skips over comments and whitespace, rejects text and refs. Also returns position of element.) The list of strings argument is for error reporting - it usually represents a list of expected tags.

xsdElement :: Name -> XsdParser (Element Posn) Source #

Get the next content element, checking that it has the required tag belonging to the XSD namespace.

anyElement :: XsdParser (Element Posn) Source #

Get the next content element, whatever it is.

allChildren :: XsdParser a -> XsdParser a Source #

Grab and parse any and all children of the next element.

interiorWith :: (Content Posn -> Bool) -> XsdParser a -> Element Posn -> XsdParser a Source #

Run an XsdParser on the child contents of the given element (i.e. not in the current monadic content sequence), filtering the children before parsing, and checking that the contents are exhausted, before returning the calculated value within the current parser context.

attribute :: QName -> TextParser a -> Element Posn -> XsdParser a Source #

Check for the presence (and value) of an attribute in the given element. Absence results in failure.

namespaceAttrs :: Element Posn -> XsdParser [Namespace] Source #

Grab any attributes that declare a locally-used prefix for a specific namespace.

matchNamespace :: String -> Attribute -> Bool Source #

Predicate for whether an attribute belongs to a given namespace.

tidy :: t -> Result x a -> Result t a Source #

Tidy up the parsing context.

targetPrefix :: Maybe TargetNamespace -> [Namespace] -> Maybe String Source #

Given a URI for a targetNamespace, and a list of Namespaces, tell me the prefix corresponding to the targetNamespace.

lookupBy :: (a -> Bool) -> [a] -> Maybe a Source #

An auxiliary you might expect to find in Data.List

qual :: Maybe TargetNamespace -> [Namespace] -> String -> String -> QName Source #

Turn a qualified attribute value (two strings) into a qualified name (QName), but excluding the case where the namespace prefix corresponds to the targetNamespace of the current schema document.

schema :: Parser (Content Posn) Schema Source #

Parse a Schema declaration

annotation :: XsdParser Annotation Source #

Parse a (possibly missing) xsd:annotation element.

definiteAnnotation :: XsdParser Annotation Source #

Parse a definitely-occurring xsd:annotation element.

qform :: TextParser QForm Source #

Parse a FormDefault attribute.

final :: TextParser Final Source #

Parse a Final or Block attribute.

schemaItem :: (String -> String -> QName) -> XsdParser SchemaItem Source #

Parse a schema item (just under the toplevel xsd:schema)

complexItem :: (String -> String -> QName) -> XsdParser ComplexItem Source #

Parse the alternative contents of a xsd:complexType decl.

particle :: (String -> String -> QName) -> XsdParser Particle Source #

Parse a particle decl.

particleAttrs :: (String -> String -> QName) -> XsdParser ParticleAttrs Source #

Parse a particle decl with optional attributes.

nameAndType :: (String -> String -> QName) -> Element Posn -> XsdParser NameAndType Source #

Parse name and type attributes.

occurs :: Element Posn -> XsdParser Occurs Source #

Parse an occurrence range from attributes of given element.

uri :: TextParser String Source #

Text parser for a URI (very simple, non-validating, probably incorrect).

string :: TextParser String Source #

Text parser for an arbitrary string consisting of possibly multiple tokens.

bool :: TextParser Bool Source #

Parse a textual boolean, i.e. "true", "false", "0", or "1"

use :: TextParser Use Source #

Parse a "use" attribute value, i.e. "required", "optional", or "prohibited"

processContents :: TextParser ProcessContents Source #

Parse a "processContents" attribute, i.e. "skip", "lax", or "strict".

qname :: (String -> String -> QName) -> TextParser QName Source #

Parse an attribute value that should be a QName.

name :: TextParser Name Source #

Parse an attribute value that should be a simple Name.
