The following demo shows two possible methods. Both require you to use the & named entity to show other named entities but, the rest of the code is literal:

Code:

<html>
<head>
<title>Show Code - Demo</title>
</head>
<body>
<textarea cols="140" rows="3" readonly style="font-family:arial;overflow:hidden;border:none;white-space:wrap;">
Hi, &amp;nbsp; <table><tr><td><a href="#">Top</a></td></tr></table><br>The quick gray fox jumped over the slow brown dog.<br>&amp;nbsp;<p align="center">Sally sells seashells down by the seashore</p> 
</textarea>
<br>
<input type="text" readonly style="font-family:arial;border:none;" value="<br>&amp;nbsp;<br>">
</body>
</html>

Note, however, that as long as you have <> where they shouldn't be, whether it shows or not, the page won't be valid.

My advice is to just run the code through a text editor's "replace."

That's got to be high on my list of reasons to [expletive deleted] the validator. Utter nonsense if true.

Not really... you have to consider HTML's XML background. An XML parser doesn't care what the tag actually does in an HTML page: all it sees is one tag inside another.

Fortunately browsers are still being coded with more common sense in mind than that.

HTML has an SGML background, and as such it's slightly more forgiving than XML (and thus XHTML). The latter will not allow any literal occurances of < or & unless they begin an element or entity reference, respectively.

However, in this case, both SGML and XML require that < is escaped as < if followed immediately by a letter as that matches the grammar production for an opening tag. The content of a textarea element is described as PCDATA (parsed character data) and is sensitive to markup-like constructs.

They are being bloated with the code that is necessary to make them useful. That isn't a good thing in my opinion; it just encourages more junk. As Twey suggested, search and replace is your friend.

I agree, and so does the W3C; that's what XHTML is all about.

We'll probably never agree on this, I'm just happy to see Mike is back! I was worried about you, old friend.
