Automatically wraps groups of headings (h1, h2, h3, h4, h5 and h6) into hgroups. Good for HTML5 styling.

CreateHGroups.js

jQuery(document).ready(function($){

var skip = 0;
$('h1, h2, h3, h4, h5, h6').each(function(i) {
    if (skip > 0) {
        skip--;
        return;
    }
    var group = $(this).add($(this).nextUntil(':not(h1, h2, h3, h4, h5, h6)'));
    skip = group.length - 1;
    if (group.length > 1) {
        if (group.parent().length && !group.parent().is('hgroup')) {
            group.wrapAll('<hgroup/>');
        }
    }
});

});
