I have XHTML pages that I deliver as application/xhtml+xml
I used to have a Javascript that hid an e-mail address from spam bots, but
displayed properly the e-mail address on web browsers.
How would you show an e-mail address in the browser but protecting it from
spam bots?
What works for text/html doesn't for application/xhtml+xml, such as
document.write...
Do you have a solution?
Thanks,

Well stop it ! (read Appendix C or c.i.w.a.h )

So your problem is nothing to do with email addresses at all, and is
really to do with how to embed JavaScript inside XHTML, without it
being non-well-formed XML.

Either hold the JavaScript in an external document, or use a CDATA
section.

I created a page with an embedded JS protected by CDATA. The page is sent
with MIME type application/xhtml+xml:
http://www.auriance.com/clientes/cpe/essai2.php
It works fine with Opera, IE (sent as text/html in this case), but with
Firefox it won't show the email address.

With Mozilla/Firefox and Opera you can't use document.write in
application/xhtml+xml.
With Mozilla/Firefox you can't use innerHTML either with that content type.
Here is an example to solve the task using DOM scripting:
<http://home.arcor.de/martin.honnen/javascript/200412/test2004122302.xhtml>

I am not sure however that approach to the email harvesting protection
is a viable one but perhaps you can use the script code.

Why not post this to c.i.w.a.h instead ? The script author is a
regular poster there.

Your script is built out of dodgy IE-specific JScript.

e.innerHTML = "<a href=\"mailto:" + address + "\">" + address +
"</a>";


I haven;'t looked closely, but I think Opera supports this, Mozilla /
Firefox don't (sadly). You can achieve similar results in a compliant
manner, but with a _lot_ more code -- you'd need to create a <link>
element as a JavaScript object with document.createElement() and then
insert it into the HTML document with HTMLDomElement.appendChild()

At last! Thanks, it's working on "major" browsers, including Opera that I
use as default browser.
Take care,

Please <a href="mailto:merlyn@stonehenge.com">send

That's sufficient for today's bots. Unlikely need to change, because
there's SOO many low hanging fruit there. No Javascript required. Nothing
fancy. Just replace the @ with @ and you're done.

Spammers do *not* de-entitize. This has been observed repeatedly. There's
no point in working harder than you must.

If you have a report or similar saying that, I would be interested in
reading it (sounds like I don't believe you, I know, but that's not the
case
