Description
This module wraps the Expat API directly, with IO.
Synopsis
data Parser

parse :: Parser -> String -> Bool -> IO (Bool)
type StartElementHandler = String -> [(String, String)] -> IO ()
type EndElementHandler = String -> IO ()
type CharacterDataHandler = String -> IO ()
setStartElementHandler :: Parser -> StartElementHandler -> IO ()
setEndElementHandler :: Parser -> EndElementHandler -> IO ()
setCharacterDataHandler :: Parser -> CharacterDataHandler -> IO ()
Parser Setup
data Parser Source
newParser :: Maybe String -> IO ParserSource

Create a Parser. The optional parameter is the default character encoding, and can be one of

  • "US-ASCII"
  • "UTF-8"
  • "UTF-16"
  • "ISO-8859-1"
Parsing
parse :: Parser -> String -> Bool -> IO (Bool)Source
parse data False feeds mode data into a Parser. The end of the data is indicated by passing True for the final parameter. parse returns False on a parse error.
Parser Callbacks
type StartElementHandler = String -> [(String, String)] -> IO ()Source
The type of the "element started" callback. The first parameter is the element name; the second are the (attribute, value) pairs.
type EndElementHandler = String -> IO ()Source
The type of the "element ended" callback. The parameter is the element name.
type CharacterDataHandler = String -> IO ()Source
The type of the "character data" callback. The parameter is the character data processed. This callback may be called more than once while processing a single conceptual block of text.
setStartElementHandler :: Parser -> StartElementHandler -> IO ()Source
Attach a StartElementHandler to a Parser.
setEndElementHandler :: Parser -> EndElementHandler -> IO ()Source
Attach an EndElementHandler to a Parser.
setCharacterDataHandler :: Parser -> CharacterDataHandler -> IO ()Source
Attach an CharacterDataHandler to a Parser.
