Phantomjs dump dom object - phantomjs

Question

I'm new to Phantomjs. For debugging on a remote server, I often want to dump a DOM object to look at the structure (similar to Data::Dumper in Perl). This currently is for scraping a couple of sites.
I've thought JSON.stringify may help with this, but it still displays an object name like "[object HTMLDocument]"
Edit: I have also looked at JavaScript: how to serialize a DOM element as a string to be used later? , but I can't seem to inject jquery in phantomjs (still looking for a solution to that, and would prefer no depencencies), and the other answer doesn't seem to work. As I assume it would be a common case for Phantom to analyse the DOM, I thought it would be common for phantom users to have a solution to this.
var page = require('webpage').create();
var system = require('system');
page.onConsoleMessage = function(msg) {
console.log( msg );
}
page.open('http://www.test.com', function(status) {
if(status !== "success") {
console.log( status );
} else {
page.evaluate(function() {
var headline = document.querySelectorAll('div');
console.log( JSON.stringify( headline ) ); // HERE???
});
}
phantom.exit();
});
Is there any way to do this, or am I approaching this wrong ?

Answer 1

in page.evaluate(), you can use XMLSerializer.serializeToString() to convert whatever DOM node you want to string.
page.evaluate(function() {
var s = new XMLSerializer();
return s.serializeToString(document.getElementById('div'));
});
I haven't tried it with "querySelectorAll", since it may return array instead of standalone DOM node, but it definitely works for DOM nodes.
