I have a bunch of old web pages now in HTML 4.01 Strict I update every
now and then with revised material. They were written back when using <a
name=" was the normal method of including an anchor. Most of the
internal anchors follow a very standard layout, and are associated with
an h3 heading.
I was wondering whether there was any reason not to change these <a
name=" anchors to <h3 id=" anchors? I gather that all recent browsers
work fine with id on any element as an anchor. I also gather that name
is deprecated in one or another of the XHTML versions I am not yet using
due to IE. I did think it might be handy in future to be a little closer
to XHTML, if I do decide I am tired of catering to IE.
I would be making other global changes to all the pages, so this change
simply adds another few sets of global replacements to my work.

Not really, unless you're doing some scripting that needs id attributes
for the elements.

Right. We can virtually ignore Netscape 4 these days.
I also gather that name
is deprecated in one or another of the XHTML versions
That's irrelevant. (Technically, it's deprecated for <aelements, but
not for all elements. The reason for the deprecation, as you know, is
that the id attribute is more logical and XML-like for the purpose.)
I did think it might be handy in future to be a
little closer to XHTML, if I do decide I am tired of catering to IE.
It doesn't matter. If you ever switch to XHTML, you will have several
changes to be made anyway, and making _this_ change is not really
special. You might use id for new pages, just as you might use
lowercase-only element names, because these are allowed in classic HTML
as well as required in XHTML. But changing existing <a name= ...>
anchors or existing use of uppercase in element names is just pointless.
_Any_ change, no matter how automated, involves a risk of errors; some
assumptions may just fail, and your regular expression (or whatever) may
somehow miss some special case and produce a mess. It's better to take
risks only when there is something to be won, i.e. when performing the
(full) conversion to XHTML for some real reason.

I can't think of any. IIRC, a very old version of Netscape honored
name= but not =id, but that's been quite a few years now. Just be
careful in your script to remove the associated </a>, even if it's
not on the same line.

Many thanks. That old Netscape was probably what I was recalling as a
possible reason not to make the changes.
Thanks for mentioning the associated </a>. I did handle that correctly,
for once. The first few sets of changes I made did reveal that some of
my earlier pages were less like the later ones than I originally
expected. Perils of not using a program to generate my web pages.
There were some errors. The mess that Jukka (correctly) predicted did
occur, however only visible in a dozen or so pages. I had no doubt I
would find other flaws when I validated some of the pages again.
The big error was that id can not start with a number, and all my names
were actually automatically generated dates like 20080107a 20080107b and
so on. I wonder why that did not throw up a validation error when I had
<a name="20080107a " I had never noticed that I had thousands of such
name errors.
I can certainly see why Jukka cautions against taking risks with regular
expression changes over heaps of files. However I only seem to improve
by running up against vast numbers of my past errors.

I used similar names to anchor revision points in my pages. When I
switched to IDs I got the same validation errors you did, so I
prepended a U to them.
I remember researching the issue, but it was a few years ago. I can't
remember whether names starting with numerics were legal in name=, or
were illegal but just not found by the validator.

I don't know if the validator ever checked values on the name attribute,
though.

No a NAME and ID must start with a letter [A-Z,a-z] http://www.w3.org/TR/html4/types.html#type-name
