Question

All of the examples I see for htmlunit retrieve the HTML from website via a URL using getPage.

WebClient webClient = new WebClient();
HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net");

I’m holding an HTML fragment in a string variable and can’t find a way to give it the HTML from a variable.

I’ve tried casting the String to HtmlPage but that doesn’t work.

HtmlPage page = (HtmlPage) htmlFragment

Perhaps you could write the HTML fragment (possibly wrapped in the standard html/head/body tags) into a temp file and use its URL for your web client. For example (untested):

File tempFile = File.createTempFile("fragment", "html");
HtmlPage startPage = webClient.getPage(tempFile.toURI().toURL().toString());
tempFile.deleteOnExit();

Alternatively, you might be able to construct your own HtmlPage with a phony URL and ad-hoc WebResponse and WebWindow but that might require a lot of hacking.
