Is it possible to read the raw HTML content of a web page that has been loaded into a UIWebView?

If not, is there another way to pull raw HTML content f

    In Swift v3:

    let doc = webView.stringByEvaluatingJavaScript(from: "document.documentElement.outerHTML")

    UIWebView

    get HTML from UIWebView`

    let content = uiWebView.stringByEvaluatingJavaScript(from: "document.body.innerHTML")

    set HTML into UIWebView

    //Do not forget to extend a class from `UIWebViewDelegate` and nil the delegate

func someFunction() {

    let uiWebView = UIWebView()
    uiWebView.loadHTMLString("<html><body></body></html>", baseURL: nil)
    uiWebView.delegate = self as? UIWebViewDelegate
}

func webViewDidFinishLoad(_ webView: UIWebView) {
    //ready to be processed
}

    [get/set HTML from WKWebView]

    if you want to extract the contents of an already-loaded UIWebView, -stringByEvaluatingJavaScriptFromString. For example:

    NSString  *html = [webView stringByEvaluatingJavaScriptFromString: @"document.body.innerHTML"];

    To get the whole HTML raw data (with <head> and <body>):

    NSString *html = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.outerHTML"];
