JSoup is a library for working with real-world HTML. It parses HTML and provides a convenient API for extracting and manipulating data. JSoup is similar to TagSoup as they both lets you work with real-world HTML, but JSoup provide more functionality for working with the extracted result.

Example Usage

To use JSoup you have to make it handler verbs available. This is easiest done by importing them from JSoupHttp.

import dispatch.jsoup.JSoupHttp._

Now we can use the operators </>, jsouped, as_jsouped and as_jsoupedNodeSeq in our handlers. As a start we can extract the title from a HTML page.

import dispatch.jsoup.JSoupHttp._

val title = Http(:/("example.org") </> { doc =>

JSoup parse the HTML to a DOM like structure org.jsoup.nodes.Document. There is a rich set of find and search methods returning org.jsoup.nodes.Elements. Elements implements java List so they are very easy to use with scala collections, just make the usual import scala.collection.JavaConversions._.

So, to extract all links from a page and put them in a list as absolute paths looks like this:

import dispatch.jsoup.JSoupHttp._
import scala.collection.JavaConversions._

val request = :/("example.org") / "test.html"
val list = Http(request </> { doc =>

JSoup is a great api for processing HTML, and scala makes it even better. To learn more of it’s capabilities take a look in the JSoup Cookbook.
