I know you may think this question is stupid, but I need to use HtmlUnit. However, it returns a page either as XML or as text.
I don't how to get the pure HTML (the same as the source code that browsers return)
I need this, because I need to use some written modules. Any ideas?
You can use the following piece of code to achieve your goal:
WebClient webClient = new WebClient();
Page page = webClient.getPage("http://example.com");
WebResponse response = page.getWebResponse();
String content = response.getContentAsString();
See javadocs of the WebResponse.html#getContentAsString() method.
