Text.XML.HaXml.SAX
Description
A streaming XML parser, using a method known as SAX. SAX isn't really a standard, but an implementation, so it's just an "SAX-like" parser. This module allows you parse an XML document without having to evaluate it as a whole. This is needed for protocols like jabber, which use xml streams for communication.
- data SaxElement
- saxParse :: String -> String -> ([SaxElement], Maybe String)
