$c = HtmlPageCrawler::create('<div id="content"><h1>Title</h1></div>');

// the above is the same as calling:
$c = new HtmlPageCrawler('<div id="content"><h1>Title</h1></div>');

// filter for h1 elements and wrap them with an HTML structure
$c->filter('h1')->wrap('<div class="innercontent">');

// return the modified HTML
echo $c->saveHTML();
// or simply:
echo $c; // implicit __toString() calls saveHTML()
// will output: <div id="content"><div class="innercontent"><h1>Title</h1></div></div>
