Text.XML.HaXml.XmlContent.Parser

Description

The class XmlContent is a kind of replacement for Read and Show: it provides conversions between a generic XML tree representation and your own more specialised typeful Haskell data trees.

If you are starting with a set of Haskell datatypes, use DrIFT to derive instances of this class for you: http://repetae.net/john/computer/haskell/DrIFT If you are starting with an XML DTD, use HaXml's tool DtdToHaskell to generate both the Haskell types and the corresponding instances.

This unified class interface replaces two previous (somewhat similar) classes: Haskell2Xml and Xml2Haskell. There was no real reason to have separate classes depending on how you originally defined your datatypes. However, some instances for basic types like lists will depend on which direction you are using. See Text.XML.HaXml.XmlContent and Text.XML.HaXml.XmlContent.Haskell.

class XmlAttributes a where Source #

The XmlAttributes class promises that a list of XML tag attributes can be converted to and from a Haskell value.

Methods

fromAttrs :: [Attribute] -> a Source #

toAttrs :: a -> [Attribute] Source #

class XmlAttrType a where Source #

The XmlAttrType class promises that an attribute taking an XML enumerated type can be converted to and from a Haskell value.

Auxiliaries for writing parsers in the XmlContent class

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.

content :: String -> XMLParser (Content Posn) Source #

The most primitive combinator for XMLParser - get one content item.

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

A specialisation of posnElementWith (==).

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.

inElement :: String -> XMLParser a -> XMLParser a Source #

A combination of element + interior.

text :: XMLParser String Source #

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

attributes :: XmlAttributes a => Element Posn -> XMLParser a Source #

Do some parsing of the attributes of the given element

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.)

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

Like element, only permits a more flexible match against the tagname.

inElementWith :: (String -> String -> Bool) -> String -> XMLParser a -> XMLParser a Source #

A combination of elementWith + interior.

choice :: XmlContent a => (a -> b) -> XMLParser b -> XMLParser b Source #

'choice f p' means if parseContents succeeds, apply f to the result, otherwise use the continuation parser.

definite :: XmlContent a => XMLParser a -> String -> String -> XMLParser a Source #

not sure this is needed now. 'definite p' previously ensured that an element was definitely present. Now I think the monad might take care of that for us.

Auxiliaries for generating in the XmlContent class

mkElem :: XmlContent a => a -> [Content ()] -> Content () Source #

Generate an element with no attributes, named for its HType.

mkElemC :: String -> [Content ()] -> Content () Source #

Generate an element with no attributes, named directly.

mkAttr :: String -> String -> Attribute Source #

Generate a single attribute.

toText :: String -> [Content ()] Source #

Turn a simple string into XML text.

toCData :: String -> [Content ()] Source #

Turn a string into an XML CDATA section. (i.e. special characters like & are preserved without interpretation.)

Auxiliaries for the attribute-related classes

data Defaultable a Source #

If an attribute is defaultable, then it either takes the default value (which is omitted from the output), or a non-default value (which obviously must be printed).

Constructors

Default a 
NonDefault a

attval :: Read a => Element i -> a Source #

Read a single attribute called "value".

catMaybes :: [Maybe a] -> [a] #

The catMaybes function takes a list of Maybes and returns a list of all the Just values.

Examples

Expand

Basic usage:

>>> catMaybes [Just 1, Nothing, Just 3]
[1,3]

When constructing a list of Maybe values, catMaybes can be used to return all of the "success" results (if the list is the result of a map, then mapMaybe would be more appropriate):

>>> import Text.Read ( readMaybe )
>>> [readMaybe x :: Maybe Int | x <- ["1", "Foo", "3"] ]
[Just 1,Nothing,Just 3]
>>> catMaybes $ [readMaybe x :: Maybe Int | x <- ["1", "Foo", "3"] ]
[1,3]

Types useful for some content models

data List1 a Source #

The List1 type represents lists with at least one element. It is required for DTD content models that use + as a modifier.

Methods

(/=) :: List1 a -> List1 a -> Bool #

data ANYContent Source #

A type corresponding to XML's ANY contentspec. It is either a list of unconverted xml Content or some XmlContent-able value.

Parsing functions (e.g. parseContents) will always produce UnConverted. Note: The Show instance for UnConverted uses verbatim.

Constructors

forall a.(XmlContent a, Show a) => ANYContent a 
UnConverted [Content Posn]
