file_get_contents with preg_match receives errors

I am trying to get some data of a website (taste.com.au) but i am not successful at getting data of an element with no class or id.

Here is my code:

$url = "http://www.taste.com.au/recipes/15281/asparagus+with+sun+dried+tomatoes+and+basil";
$html = file_get_contents($url);

This one works:

preg_match("/<h1 itemprop=\"name\">(.*)<\/h1>/i", $html, $title);
echo $title;

Where the html is:

<td class="prepTime">
    <em itemprop="prepTime">0:10</em> //Data i want
    <p>To Prep</p>
</td>

But i am not sure how to get the data of code like this:

<td class="cookTime">
    <em>0:15</em> //Data i want
    <p itemprop="cookTime" datetime="PT15M">To Cook</p>
</td>

**UPDATE: **Im still in need of help, i've tried adding in the start of the tag after it, still doesnt work.

Alternatively, you might want to use DOMXPath to traverse and find your desired values. Consider this example:

$url = "http://www.taste.com.au/recipes/15281/asparagus+with+sun+dried+tomatoes+and+basil";
$html = file_get_contents($url);
$dom = new DOMDocument();
@$dom->loadHTML($html);

$finder = new DomXPath($dom);
$values = $finder->query("//tr[@class='info-row']/td[@class='cookTime']/em");

foreach($values as $value) {
    echo $value->nodeValue; // 0:15
}
