I need only one example to contradict you,
that is the joy of logic:

A forwarding email-address is NOT an email-box.

It is an e-mail address, in the same way that FFFFFFFF FFFFFFFF is a
computer's RAM address, even though it might not have been installed.

Presumably you meant address of a mailbox. You should be more careful
with your terminology.

And, of course, if a mailbox does not exist in this minute that is no
proof at all that it didn't exist when the article was constructed.

How would you know my nationality or nationalities?

You would not and do not!

What could one's nationality have to do with Usenet Netiquette?

Nothing!

On the contrary, Evertjan. The guidelines for the German Usenet
hierarchy are different from the guidelines for the UK Usenet
hierarchy. That's why Netiquette depends, to some extent, on the
author's nationality. I don't need to know your nationality to be
absolutely certain that there are other people with a different
nationality. That's all I said, if you read it carefully.

You are totally wrong here.

The different usenet hierarchies have nothing to do 
with the nationality or nationalities of a specific user.
And Netiquette addresses the conduct of those.

btw, Usenet does not have authors, only users. 
Perhaps that's why it is not called Authornet.

I don't see your point.

Read exactly what carefully? 
On Usenet referring to earlier postings should be quoted.

Hi, all three of you probably belong to the top 5% of programmers. I greatly appreciate your expertise and advice and let me assume the fault of the recent arguments for the simple fact it stems from this thread which I started.  Could you guys look at the updates of the other thread about how to save an HTML page that has many dynamically generated elements via DOM?
Thanks.

But the guidelines talk of Netiquette items - attributions for
instance. Germans don't have to take any notice of the German
guidelines, but some do. Britons don't have to take any notice of the
UK guidelines, but some do. Nationality can make a difference.

Each Usenet article does have an author, or are you claiming to be an
AI entity?

See above : your nationality can make a difference, and that is so
regardless of your actual nationality. Remark : you claimed that I
didn't know your nationality; I'm pointing out that it's irrelevant.

It's already quoted at the beginning of the article. I'm not going to
quote it twice.

This cannot work because d.gEBCN() only returns a reference to an array-
*like* object which does not have a forEach() method by default.  You have 
to convert that object to an Array instance, or call 
Array.prototype.forEach() explicitly:

  [].forEach.call(elements, element => element.className = newClass);

Besides, the question was gibberish.  Your code does not replace the 
elements, it replaces the *class attribute value* of matching elements.

It remains to be seen whether that is really what the OP wants.  It is 
equally possible that they only want to exchange the class name in the 
attribute value:

  let oldClassName = "Space";
  [].forEach.call(
    document.getElementsByClassName(oldClassName),
    element => {
      element.classList.remove(oldClassName);
      element.classList.add(anotherClassName);
    });

      [We can reasonably assume that HTML user agents that provide an 
       ECMAScript 2015+ implementation for “let” and the arrow function
       syntax also support the DOM4 “classList” property.  The vice-versa
       assumption is not valid.]

Usually you would just add or remove a class name to/from the attribute 
value instead.  A stylesheet that requires renaming of a class name in
the attribute value for proper presentation is most certainly ill-designed.

The replace image inside each span with another is working now.
See my code below.  Probably previously my problem statement were not clear.
Thanks.

var connector = function() {

// get the class
	let spaceS = document.getElementsByClassName('Space');
	
	for (s = spaceS.length - 2; s >= 0; s--) {
		console.log(s);
		try {
		spaceS[s].innerHTML = "<img src='line.png' border=0>";
		}
		catch (err) {
			consolo.log(err);
		}
	}
	
}

What do you mean by "not satisfactory"?
Usenet is not a restaurant were you order and pay for food.

Methinks the discussions I refer to are very, very satisfactory,
in the sense that you learn the different aspecs and the pit-falls of
the matter at hand.

I appreciate your intention and help, however, regarding this particular problem, googling has not helped me to resolve it, hence, here again.

Did you get a better understanding of the matter?
