Hi, I'm one of those from forensic world and, of course, my use case needs to extract everything.
I have already tried IdentityHtmlMapper to extract "value" attributes from "input" elements with no luck. It is not extracted by DefaultHtmlMapper and is rendered by browsers, so I think DefaultHtmlMapper needs some improvement. But HtmlMapper is the correct place to configure that or something must be done with HTMLSchema (I've tried that too, but I am not a html expert)?
