Question

How can I get the WordPress language_attributes function to return valid XHTML 1.1?

Answer 1

A:

If this is just a theme on your own site, you could edit header.php and change the

<html xmlns="http://www.w3.org/1999/xhtml" <?php language_attributes('xhtml'); ?>>

line to be hardcoded, improves performance too :-)

That's an option. But I'm not sure to what other uses the client may put the template, so, if I can, I'd like to retain that functionality.

Answer 2

A:

I solved this. There's a "language_attributes" filter, so I wrote a plugin that hooks into that and does a simple preg_replace. The replace worked when performed here, and it's a pretty neat way to handle it.

EDIT

As requested, here's the code I used:

<?php
/*
Plugin Name: Create Valid XHTML 1.1
Plugin URI: http://www.mycompany.com/create_valid_xhtml_1_1
Description: Removes deprecated "lang" attribute from (X)HTML header.
Author: dommer
Version: 1.0.0
Author URI: http://www.mycompany.com
*/

function create_valid_xhtml_1_1($language_attributes) 
{
    return preg_replace('/ lang=\"[a-z]+\-[A-Z]+\"/', '', $language_attributes);
}

add_filter('language_attributes', 'create_valid_xhtml_1_1');
?>

A:

Could you list the filter you wrote for other to come? It will be really helpful for me. Thanks.
