Types
Parsing XML
tokens :: Monad m => Splitter m Char (Boundary Token)Source
The tokens splitter distinguishes XML markup from data content. It is used by parseTokens.
parseTokens :: Monad m => Parser m Char TokenSource
The XML token parser. This parser converts plain text to parsed text, which is a precondition for using the remaining XML components.
expandEntity :: String -> StringSource
Converts an XML entity name into the text value it represents: expandEntity "lt" = "<".
Showing XML
escapeAttributeCharacter :: Char -> StringSource
Escapes a character for inclusion into an XML attribute value.
escapeContentCharacter :: Char -> StringSource
Escapes a character for inclusion into the XML data content.
Splitters
element :: Monad m => Splitter m (Markup Token Char) ()Source
Splits all top-level elements with all their content to true, all other input to false.
elementContent :: Monad m => Splitter m (Markup Token Char) ()Source
Splits the content of all top-level elements to true, their tags and intervening input to false.
elementName :: Monad m => Splitter m (Markup Token Char) ()Source
Splits every element name, including the names of nested elements and names in end tags, to true, all the rest of input to false.
attribute :: Monad m => Splitter m (Markup Token Char) ()Source
Splits every attribute specification to true, everything else to false.
attributeName :: Monad m => Splitter m (Markup Token Char) ()Source
Splits every attribute name to true, all the rest of input to false.
attributeValue :: Monad m => Splitter m (Markup Token Char) ()Source
Splits every attribute value, excluding the quote delimiters, to true, all the rest of input to false.
SplitterComponent combinators
elementHavingTag :: forall m b. MonadParallel m => Splitter m (Markup Token Char) b -> Splitter m (Markup Token Char) bSource
Similiar to (, except it runs the argument splitter
only on each element's start tag, not on the entire element with its content.
Control.Concurrent.SCC.Combinators.having element)
havingText :: forall m b1 b2. MonadParallel m => Bool -> Splitter m (Markup Token Char) b1 -> Splitter m Char b2 -> Splitter m (Markup Token Char) b1Source
Behaves like Control.Concurrent.SCC.Combinators.having, but the right-hand splitter works on plain instead of
marked-up text. This allows regular Char splitters to be applied to parsed XML.
havingOnlyText :: forall m b1 b2. MonadParallel m => Bool -> Splitter m (Markup Token Char) b1 -> Splitter m Char b2 -> Splitter m (Markup Token Char) b1Source
Behaves like Control.Concurrent.SCC.Combinators.havingOnly, but the right-hand splitter works on plain instead of
marked-up text. This allows regular Char splitters to be applied to parsed XML.
