FBML W3C peace of mind
Some time ago I've connected the blog to Facebook using MyApi.co.uk.
It works great, but W3C validator believes fb: tags break the markup.
To whom it does matter, the simple workaround with XHTML markup is to hide the tags inside CDATA.
<script type="text/javascript">/* <![CDATA[ */
document.write('<fb:***></fb:***>');
/* ]]> */</script>
a piece of code to wrap a $newdata variable containing FBML looks like this:
$newtext = '<script type="text/javascript">/* <![CDATA[ */ document.write(\''.$newtext.'\');/* ]]> */</script>';
That's it.
