Facebook: Invalid mark up on FBML

I am using the W3C XHTML validator to check my sites and I am getting some errors on pages with FBML. Most of the cause of such errors is the "&" character. Since FBML values and attributes are generated on the fly, I have no way to encode the character properly before displaying it.

Question: Is there a way for me to tell Facebook Connect to render the mark up properly?

Thanks.

Try to put the facebook code in CDATA:

<script type="text/javascript">
/* <![CDATA[ */ 
document.write('<fb:login-button length="long" size="large" show-faces="true" perms="" onlogin="window.location=\'<?=current_url()?>\'"></fb:login-button>'); 
/* ]]> */
</script>

In short, not as far as I know. To make matters worse, the fb:* tags don't validate either, even if you make your html tag look like this:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml" xml:lang="en" lang="en">

If this is a huge issue for you, you might be able to get away with putting non-XHTML-compliant markup in its own HTML-4.01-strict iframe, to basically sweep the crap under the rug.

This might be helpful:

Some german guy also worked on it:

This is how i am doing it. Wrap around all fbml tags inside and then use js to simply uncomment the fbml code using javascript. Heres an example:

Markup:

<P class="fbreplace" style="display: none;">
    <!-- FBML
        <fb:like layout="standard" show_faces="false" colorscheme="light"></ fb: like>
    ->
</ p>

JS (JQuery Required):

$(document).ready(function() {
  $(".fbreplace").html.replace(/<!-- FBML /g, "");
  $(".fbreplace").html.replace(/ -->/g, "");
  $(".fbreplace").style.display = "block";
});

This is interesting. There are better ways to do it but I just can't help but say that this is really interesting. And it works! – Bowstring
