I'm dynamically populating a TEXTAREA with some info that includes a
URL. Eg.

frm.value = "This is the link to use <url: http://www.foo.com >";

but this results in a page that doesn't validate. I tried escaping the
value but then I get entities displaying in the TEXTAREA.

Is there a way to change the value without upsetting the page's validation?

What does it complain about? The <url tag?

Put the script in an external file, the validator will never see it.

I get 3 specific errors:
- Warning: discarding unexpected </textarea>
- Warning: <url:> attribute "http://www.foo.com" lacks value
- Error: <url:> is not recognized!

It's not the script per se but the content of the TEXTAREA that is
causing the validator to barf.

That's because <url: http://www.foo.com > isn't a well formed HTML tag.

So the validator validating the page after your script has modified it.
If the script where in another file, the validation might not include it.

I guess you use XHTML validation. So validator does not like the
unknown unclosed tag <url:> with incorrect attribute. You can avoid it
if you change "This is the link to use <url: http://www.foo.com >" to
plain text. Replace < with &lt; and replace > with &gt;.

>> frm.value = "This is the link to use <url: http://www.foo.com >";

frm is textarea, yes?
Try this.
frm.innerHTML = "This is the link to use &lt;url: http://www.foo.com
&gt;";

Actually, in my initial tests I use the TIDY add-on for FF 2.

Unfortunately I think I have to put up with it not being valid as using
the method above displays &alt; and not < in the TEXTAREA.

What does the W3C Validator say about the same code? If the W3C
Validator doesn't complain but Tidy does then Tidy is the culprit, not
your HTML.

Use the W3C validator.

That may be so for Genuine Errors.

But :

(1) Tidy gives by default warnings which are not by default given by
<http://validator.w3.org/>.

(2) <http://validator.w3.org/> gives up on at least one page - an ISP's
Home Page, forsooth - for which TIDY will happily report usefully on a
local copy. W3 hates characters not in the character set.

IMHO, it's worth using both. I have a batch file which runs TIDY and
various other tests (including checking for 8061) on any HTML page here
that's changed since the last time, stopping on error but otherwise
running to completion.
