Text

type Text = Alt Text

Parser in the context of a textual value.

text :: (Text -> Either Text a) -> Text a

Lifts an arbitrary textual parser function to the text-value parser.

Provides a doorway for composition with such libraries as "parsec" or "attoparsec".

Derivatives

textValue :: Text Text

Simply extracts the textual value.

Element

type Element = Alt Element

elementNameText :: Text a -> Element a

elementAttr :: Attr a -> Element a

Parses one of element's attributes without any regard to order.

elementNodes :: Nodes a -> Element a

Parses all of element's nodes.

Can be used multiple times, thus allowing for parallel parsing of element's child-nodes. Naturally this will result in traversing the element's nodes multiple times.

Derivatives

elementNameIs :: Text -> Element ()

Attr

type Attr = Alt Attr

attrNameText :: Text a -> Attr a

Parses the attribute's name using the provided textual parser.

attrValueText :: Text a -> Attr a

Parses the attribute's value using the provided textual parser.

Derivatives

attrNameIs :: Text -> Attr ()

A parser, which succeeds if the attribute's name matches the provided value.

attrValueIs :: Text -> Attr ()

A parser, which succeeds if the attribute's value matches the provided value.

Nodes

type Nodes = Alt Nodes

A sequential backtracking parser of nodes.

nodesImmediateNode :: Node a -> Nodes a

Parses the next node.

nodesEventualNode :: Node a -> Nodes a

Parses one of the following nodes.

Node

type Node = Alt Node

nodeElement :: Element a -> Node a

nodeText :: Text a -> Node a
