Remove ‘rel’ attributes from the_category() output

1 Views

I am trying to get the categories associated with a post in it’s meta section by using the following code: 

<div>FILED AS: <span class="gf-post-meta-result"><?php the_category(' &bull; ') 
?></span></div>

WordPress is generating the markup as:

<div>FILED AS: <span class="gf-post-meta-result">
    <a href="http://localhost/test/category/uncategorized/" title="View all posts in Uncategorized" rel="category tag">Uncategorized</a>
</span></div>

This part rel="category tag" is making my code invalid. W3C validator throws an error saying:

Bad value category tag for attribute rel on element a: The string category is not a registered keyword or absolute URL. Whitespace in path component. Use %20 in place of spaces.

…w all posts in Uncategorized” rel=”category tag”>Uncategorized

Any idea how to rectify this?

  1. Filter the_category, and remove those attributes:

    add_filter( 'the_category', 't5_remove_cat_rel' );

function t5_remove_cat_rel( $list )
{
    return str_replace(
        array ( 'rel="category tag"', 'rel="category"' ), '', $list
    );
}
