crouton's Introduction

Crouton

Crouton is a HTML parsing library for Clojure that uses JSoup.

Installation

Add the following dependency to your project.clj file:

[crouton "0.1.2"]

Usage

Crouton provides a way of parsing a HTML file from a slurp-able source:

(require '[crouton.html :as html])

(html/parse "http://example.com")

The parsed result is a DOM tree compatible with that produced by clojure.xml/parse.

If you have a string, rather than a file, URL or input-stream, you can use parse-string:

(html/parse-string "<html><head></head><body></body></html>")

crouton's Issues

parse-string not in 0.1.1

Tried to pull down 0.1.1 using leiningen and start using parse-string. It said it couldn't find parse-string, though, is that not available until a later version?

Stack overflow exception in AsClojure implementation.

I accidentally parsed large GIF file (http://i.imgur.com/flMMU.gif) and this caused StackOverflowError in conversion from JSoup to Clojure data structures in implementation of AsClojure protocol in crouton/html.clj

I concede that this is not usual case and rarely happens in practice but
HTML might be specifically constructed to exploit this error or
there could be incorrect content type detection. And SOE is serious in that it is not recommended to recover from it (as well as from OutOfMemoryError).

It would be nice to limit conversion to some reasonable depth to avoid this exception.
