ssoup: Scala CSS Selector DSL based on jsoup

Install

"info.henix" %% "ssoup" % "0.5"

DO NOT use v0.3

Example

import henix.ssoup.Selectors
import Selectors._

val document = Jsoup.parse(???)
val body = select1(document |>> "body") // BFS will find <body> more quickly than DFS
val nav = select(body > "div#page" > "div#nav").headOption

val $ = Selectors.buildIdCache(document)
val footer = $("footer")

Notice

Structural selectors not allowed in string parameters: select(body > "#page > #nav") won't do what you expect. String parameters only allow selectors for a single HTML element.

Supported structural selectors

> : child
>> : traverse descendants using DFS
|>> : traverse descendants using BFS
~ : siblings
+ : immediate sibling

API

select(Iterator[Element]): Stream[Element]

Find all elements that match the selector.

select1(Iterator[Element]): Element

Find the first element that matches the selector. This macro will generate friendly error message which include the selector.

Performance Consideration

In contrast to many selectors implementations, ssoup implement selectors in a more direct way. This means:

> will iterate element's children
~ will iterate element's siblings
>> and |>> will traverse element's all descendants

So you should avoid using more than one >> or |>> in a select / select1 call.
