How to get the entire document HTML as a string?

Question

Is there a way in JS to get the entire HTML within the html tags, as a string?

document.documentElement.??

Answer 1

You have to iterate through the document childNodes and getting the outerHTML content.

in VBA it looks like this

For Each e In document.ChildNodes
    Put ff, , e.outerHTML & vbCrLf
Next e

using this, allows you to get all elements of the web page including < !DOCTYPE > node if it exists

Answer 2

document.documentElement.innerHTML

Answer 3

MS added the outerHTML and innerHTML properties some time ago.

According to MDN, outerHTML is supported in Firefox 11, Chrome 0.2, Internet Explorer 4.0, Opera 7, Safari 1.3, Android, Firefox Mobile 11, IE Mobile, Opera Mobile, and Safari Mobile. outerHTML is in the DOM Parsing and Serialization specification.

See quirksmode for browser compatibility for what will work for you. All support innerHTML.

var markup = document.documentElement.innerHTML;
alert(markup);

Answer 4

The correct way is actually:

webBrowser1.DocumentText

Answer 5

You can do

new XMLSerializer().serializeToString(document)

in browsers newer than IE 9

See https://caniuse.com/#feat=xml-serializer

Answer 6

You can also do:

document.getElementsByTagName('html')[0].innerHTML

You will not get the Doctype or html tag, but everything else...
