An interesting fact about '40' is it's prevalence in ancient times was due to astronomic observations. Hesiod, in Works And Days (about 700 BC), said:Quote: When the Pleiades, daughters of Atlas, are rising, begin your harvest, and your ploughing when they are going to set. Forty nights and days they are hidden and appear again as the year moves round, when first you sharpen your sickle.
Those '40' days of invisibility are why the number became the one for the god of the ocean/earth (and 'ocean' was associated with the imaginary 'ocean' upon which our ancestors thought the world floated):Enki ( /ˈɛŋki/) or Enkil (Sumerian: dEN.KI(G)𒂗𒆠) is a god in Sumerian mythology, later known as Ea in Akkadian and Babylonian mythology. He was originally patron god of the city of Eridu, but later the influence of his cult spread throughout Mesopotamia and to the Canaanites, Hittites and Hurrians. He was the deity of crafts (gašam); mischief; water, seawater, lake water (a, aba, ab), intelligence (gestú, literally "ear") and creation (Nudimmud: nu, likeness, dim mud, make bear). He was associated with the southern band of constellations called stars of Ea, but also with the constellation AŠ-IKU, the Field (Square of Pegasus). Beginning around the second millennium BCE, he was sometimes referred to in writing by the numeric ideogram for "40," occasionally referred to as his "sacred number." Because of that, '40' was associated with death/rebirth cycles, and used throughout the Bible (and probably myths from other cultures as well) for such symbology.
Happy '40' everyone!

40 points awarded for using Enki in an example. When you hit 50, be sure to reference his brother Enlil.

Unfortunately, I have not yet found the astronomy behind that number. Maybe I will have by then. I do know the astronomy behind '60' for Anu, so the chances of it being an astronomic cycle are exceedingly high. Hesiod said Cerberus had '50' heads, and Cerberus seems to be associated with the constellation of Hercules, so maybe it is connected to that group of stars somehow.

the ancient Sumerian text associate's Enlil's number as 50, astronomy or not.

I know. As Anu and Ea's numerical values were derived from astronomy, Enlil's probably also derives from astronomy.

Okay, I'll own up. My immediate response to the title was a mental image of the Ford GT40...

On IoT you don't have a lot of luxuries. You simply learn to do without.
Well, one area where I have to do without is HTML and XML well formedness checking and validation.
That might be an issue where data interchange is concerned, but not so much where rendering HTML or XHTML content is concerned.
What do you do on an error? You fail. You can either stop, or continue to render, possibly having some bad content displayed as a result, but this is still a better case than failing outright halfway through the parse because the document forgot a </b>. In fact, this is what commercial browsers do.
Here's the thing. If this is what you're doing, you don't need a DTD. You don't need an XSD Schema. You don't even need a heckin stack!
The result is much faster and lighter with a smaller binary footprint.
So why haven't I seen a pull reader with minimal validation/well formedness checking in the open source pool?
You'd think such a beast would be incredibly useful for building web browsers - even tiny ones - especially tiny ones!

I shouldn't have to be writing this. It's one of those things that leaves me wondering why it doesn't exist already.

It was a task waiting for you!
And look, here you are!

Why ? Because it is probably more complicated than it seems.

Remember who you are talking to. 90% of the stuff the witch does is over my head.

edit/ Nevermind - wrong thread.
Yes, you are probably very right

It's not really. I'm almost done with it.

Yes, I was merely talking about normal mortals like us, not wizards

That'd be a witch. Wizards are a different thing altogether.

I preprocess / strip out all the HTML and insert my own markup directives. I don't need a "paragraph" keyword to tell me where a paragraph should start or end; etc. But as you say, it's assumed to be valid HTML in the first place (or made to be).

As far as preprocessing I don't have the memory or nvs storage to do that on my device, and it wouldn't really buy me anything much even if i did.
Much better in my scenario at least, to just read with a pull parser in a loop, get tag names back and set values on a context structure i use while rendering. The context structure has the current position and flags like "bold" or "italic", styles and font faces, that sort of thing.
I mean, if I knew at compile time what my HTML was going to be I'd just generate C++ code from it that renders it, and that sort of "preprocessing" would be a huge win, but in my scenario I have to read arbitrary HTML.

Thanks for the vote of confidence. I'm getting there but it's a bit of a bear.
For starters, everything has to stream, because you don't have a ton of RAM. 1kB is a big deal, so i let you specify as little as 128 bytes for a buffer. I can't stream attribute and element names, but I can stream attribute values and element content, N bytes at a time (depending on what you had set N to)
So if you have a long attribute value while you're doing while(reader.read()) { you'll get multiple reader.node_type()==ml_node_type::attribute_content results back before getting reader.node_type()==ml_node_type::attribute_end
Not only are there a zillion html entities like © (©) but I had to make a state machine to decode all of them efficiently off a unicode stream.
Also this:
<span class="foo">this is valid</span>
<span class='foo'>and this</span>
<input disabled><!--
<div class=you_thought_this_would_be easy id=but_no_because_html_hates_you_this_is_also_valid></div>
<br /><!--
So this is kinda rough sometimes, but I'm making progress.
Fortunately I don't have to care about custom entity references, namespace declarations, or even well formedness (balanced tags, etc) which makes some of it pretty easy.

You bugger. The bit of my brain I need to use to make an intelligent response is entirely consumed with the act of killing myself laughing at your code-snippet. Fan-friggen-tastic

I've got it running. I even wrote most of the article, but I should probably test it more.
