1.  trait Browser extends AnyRef

   A client able to retrieve and parse HTML pages from the web and from local resources.

   A client able to retrieve and parse HTML pages from the web and from local resources.

   An implementation of Browser can fetch pages via HTTP GET or POST requests, parse the downloaded page and return a net.ruippeixotog.scalascraper.model.Document instance, which can be queried via the scraper DSL or using its methods.

   Different net.ruippeixotog.scalascraper.browser.Browser implementations can embed pages with different runtime behavior. For example, some browsers may limit themselves to parse the HTML content inside the page without executing any scripts inside, while others may run JavaScript and allow for Document instances with dynamic content. The documentation of each implementation should be read for more information on the semantics of its Document and net.ruippeixotog.scalascraper.model.Element implementations.

2.  class HtmlUnitBrowser extends Browser

   A Browser implementation based on HtmlUnit, a GUI-less browser for Java programs.

   A Browser implementation based on HtmlUnit, a GUI-less browser for Java programs. HtmlUnitBrowser simulates thoroughly a web browser, executing JavaScript code in the pages besides parsing and modelling its HTML content. It supports several compatibility modes, allowing it to emulate browsers such as Internet Explorer.

   Both the net.ruippeixotog.scalascraper.model.Document and the net.ruippeixotog.scalascraper.model.Element instances obtained from HtmlUnitBrowser can be mutated in the background. JavaScript code can at any time change attributes and the content of elements, reflected both in queries to Document and on previously stored references to Elements. The Document instance will always represent the current page in the browser's "window". This means the Document's location value can change, together with its root element, in the event of client-side page refreshes or redirections. However, Element instances belong to a fixed DOM tree and they stop being meaningful as soon as they are removed from the DOM or a client-side page reload occurs.

3.  class JsoupBrowser extends Browser

   A Browser implementation based on jsoup, a Java HTML parser library.

   A Browser implementation based on jsoup, a Java HTML parser library. JsoupBrowser provides powerful and efficient document querying, but it doesn't run JavaScript in the pages. As such, it is limited to working strictly with the HTML send in the page source.

   Currently, JsoupBrowser does not keep separate cookie stores for different domains and paths. In each request all cookies set previously will be sent, regardless of the domain they were set on. If you do requests to different domains and do not want this behavior, use different JsoupBrowser instances.

   As the documents parsed by JsoupBrowser instances are not changed after loading, Document and Element instances obtained from them are guaranteed to be immutable.

4.  case class Proxy(host: String, port: Int, proxyType: Type) extends Product with Serializable

   A proxy configuration to be used by Browsers.

   A proxy configuration to be used by Browsers.

   host

   the proxy host

   port

   the proxy port

   proxyType

   the protocol used by a proxy (e.g. HTTP, SOCKS)
