Description

A binding to curl, an efficient, high level library for retrieving files using Uniform Resource Locators (URLs).

Content may be retrieved as a strings, ByteString or parsed as HTML tags, XML or RSS and Atom feeds.

Error handling is encapsulated in the Either type.

Synopsis
openURI :: String -> IO (Either String ByteString)
openURIString :: String -> IO (Either String String)
openAsTags :: String -> IO (Either String [Tag])
openAsXML :: String -> IO (Either String [Content])
openAsFeed :: String -> IO (Either String Feed)
The basic interface to network content
openURI :: String -> IO (Either String ByteString)Source

Download content specified by a url using curl, returning the content as a strict ByteString.

If an error occurs, Left is returned, with a protocol-specific error string.

Examples: 

 openURI "http://haskell.org"
openURIString :: String -> IO (Either String String)Source

Like openURI, but returns the result as a String

Examples: 

 openURIString "http://haskell.org"
Parsers for common formats
openAsTags :: String -> IO (Either String [Tag])Source
Download the content as for openURI, but return it as a list of parsed tags using the tagsoup html parser.
openAsXML :: String -> IO (Either String [Content])Source
Download the content as for openURI, but return it as parsed XML, using the xml-light parser.
openAsFeed :: String -> IO (Either String Feed)Source
Download the content as for openURI, but return it as parsed RSS or Atom content, using the feed library parser.
