I have now seen the new Edge.  As it does not show a HOME icon, and I could not rapidly find a way of making it show one, I have lost interest in using it.

It has no URL; all this is entirely on a Windows PC, on which the only relevant non-default applications are this page and a nice browser to run it.

I am not using IIS.  I would be content to not use even a browser.


What I need is

function GetDomTree(FileName) { // File will exist
  // code
  return DomTree }

or similar.

Since the current browser implementations of the "same origin" policy exclude this case of a same origin, the question has become that of whether VBScript and/or JScript natively possesses such a function or a fairly direct means of writing one; VBScript seems much better or more widely documented than JScript, but VBScript docs + ECMA 3 suffice for JScript.

I seem to recollect reading that the VBScript API(s) include a means of generating a DOM tree; if so, I just would need to know the name of the API routine, and Google should let me find the rest.

Then, I could port my JavaScript to JScript, running with WSH at the MS-DOS Command Line, or in an HTA.  I don't know how long it would take me to do that, though.

However, I now have an alternative to running this page in Windows 10 & MSIE 11; I have revived my old WinXP PC, which has Firefox 52.9.0esr, and the page works properly there.  My normal backup scheme already gets enough onto a USB stick, and the XP PC can process it there at its leisure.


But a further question, about the DOM :

I know of these >20-year-old pseudo-array properties of the document object : anchors, links, forms, images (& applets, embeds); are there now any other "similar" objects?
