Sébastien | French WordpressDesigner comments:

i have add in my question :

edit 1 :

<strong>TWO THINGS</strong> :
1-remove the style in H-tag if there is a style
2-add a span in each H-tag (h1->h6)

and just modify my function

Martin Pham comments:


add_filter('the_content', 'replace_content',1);
function replace_content($content) {
$content = preg_replace( '/<h(\d{1,6})(.*?)>(.*?)<\/h(\d{1,6}).*?>/', '<h$1 $2><span>$3</span></h$4>', $content );
return $content;
}

Just a little little problem
with this code the inline-style is removed, but the class or the id are removed too

Martin Pham comments:

Edit :)

add_filter('the_content', 'replace_content',1);
function replace_content($content) {

$content = preg_replace( '/<h(\d{1,6})(.*?)>(.*?)<\/h(\d{1,6}).*?>/', '<h$1><span>$3</span></h$4>', $content );

return $content;

}

Rules:
<h1>This is h1</h1> ====> <h1><span>This is h1</span></h1>

<h1 class="my_class">This is h1</h1> ====> <h1><span>This is h1</span></h1>

<h1 style="color:red;">This is h1</h1> ====> <h1><span>This is h1</span></h1>

Sébastien | French WordpressDesigner comments:

yes that's what i say
with your code, results are :

<h1>This is h1</h1> ====> <h1><span>This is h1</span></h1>
<h1 class="my_class">This is h1</h1> ====> <h1><span>This is h1</span></h1>
<h1 style="color:red;">This is h1</h1> ====> <h1><span>This is h1</span></h1>

but resultats must be :
<h1>This is h1</h1> ====> <h1><span>This is h1</span></h1>
<h1 class="my_class">This is h1</h1> ====> <h1 class="my_class"><span>This is h1</span></h1>
<h1 style="color:red;">This is h1</h1> ====> <h1><span>This is h1</span></h1>

class and id must not be removed

Martin Pham comments:

Full code :)

add_filter('the_content', 'replace_content',1);
function replace_content($content) {
$content = preg_replace( '/<h(\d{1,6})(.*?)>(.*?)<\/h(\d{1,6}).*?>/', '<h$1 $2><span>$3</span></h$4>', $content );
$content = custom_strip_attr($content, array('h1', 'h2', 'h3', 'h4', 'h5', 'h6'), array('style'));
return $content;
}

function custom_strip_attr( $text, $elements, $attributes, $two_passes = true ) {
$elements_pattern = implode( '|', (array) $elements );

/** Build patterns */
$patterns = array();
foreach ( (array) $attributes as $attribute ) {
/** Opening tags */
$patterns[] = sprintf( '~(<(?:%s)[^>]*)\s+%s=[\\\'"][^\\\'"]+[\\\'"]([^>]*[^>]*>)~', $elements_pattern, $attribute );

/** Self closing tags */
$patterns[] = sprintf( '~(<(?:%s)[^>]*)\s+%s=[\\\'"][^\\\'"]+[\\\'"]([^>]*[^/]+/>)~', $elements_pattern, $attribute );
}

/** First pass */
$text = preg_replace( $patterns, '$1$2', $text );

if ( $two_passes ) /** Second pass */
$text = preg_replace( $patterns, '$1$2', $text );
return $text;

}
