Getting Final HTML with Javascript rendered Java as String

Question

I want to fetch data from an HTML page(scrape it). But it contains reviews in javascript. In normal java url fetch I am only getting the HTML(actual one) without Javascript

Answer 1

You can use HTML Unit, A java based "GUI LESS Browser". You can easily get the final rendered output of any page because this loads the page as a web browser do so and returns the final rendered output. You can disable this behaviour though.

UPDATE: You were asking for example? You don't have to do anything extra for doing that:

Example:

WebClient webClient = new WebClient();
HtmlPage myPage = ((HtmlPage) webClient.getPage(myUrl));

UPDATE 2: You can get iframe as follows:

HtmlPage myFrame = (HtmlPage) myPage.getFrameByName(myIframeName).getEnclosedPage();

Please read the documentation from above link. There is nothing you can't do about getting page content in HTMLUnit
