How to convert string from [object HTMLDocument] in android or java

Question

I am developing a customized gecko powered android browser. I want to print the source code in console.

When I try to print it shows [object HTMLDocument].

The code is given below :

 function onPageLoad(event) {
   // the target is an HTMLDocument
   let contentDocument = event.target;
 let browser = BrowserApp.getBrowserForDocument(contentDocument);
   console.log("Page loaded: " + browser.contentTitle);
   console.log("Page loaded content: " + browser.contentDocument);

 }

The output is Page loaded content: [object HTMLDocument]

I want to print the source code in [object HTMLDocument].

Ah, I see. Try:

let contentDocument = event.target;
console.log("Page loaded: " + contentDocument.title);
var s = new XMLSerializer().serializeToString(contentDocument);
console.log("Page loaded content: " + s);

This worked for me at least (if I understand correctly what you want to print that is).

The output shows "Page loaded content: undefined". The codes are written in javascript file.

which is the import file for XMLSerializer in android studio. I have got an error is JavaScript Error: "ReferenceError: XMLSerializer is not defined"

I think it is "import org.xmlpull.v1.XmlSerializer;", hope it works!

Have you tried converting it to a String? For example, console.log("Page loaded: " + String(browser.contentTitle));

Try this:

HTMLEditorKit tmp = new HTMLEditorKit(); 
HTMLDocument doc = (HTMLDocument) tmp.createDefaultDocument(); 
StringWriter writer = new StringWriter();
tmp.write(writer, doc, 0, doc.getLength());
String s = writer.toString();
console.log(s);

I hope it will help.

Put , instead of + in console.log() function as console.log() also support object. Just you need to separate by comma.

console.log("Page loaded: " , browser.contentTitle);
console.log("Page loaded content: " , browser.contentDocument);

The output is I/Gecko: console.log: Page loaded: Asset Test I/Gecko: console.log: Page loaded content: HTMLDocument {"location":{"href":"resource://android/assets/test.html","origin":"resource://android","protocol":"resource:","username":"","password":"","host":"android","hostname":"android","port":"","pathname":"/assets/test.html","search":"","hash":""}}

using comma is not possible.

It's just showing what it contains. browser.contentTitle and browser.contentDocument do not contains any source code. I guess event.target would give you source code.
