How to combine the text node of 2 pieces of extracted data using Goutte/Domcrawler

I've been trying to figure out how to combine two pieces of extracted text into a single result (array). In this case, the title and subtitle of a variety of books. 

<td class="item_info">
  <span class="item_title">Carrots Like Peas</span>
  <em class="item_subtitle">- And Other Fun Facts</em>
</td>

The closest I've been able to get is:

$holds = $crawler->filter('span.item_title,em.item_subtitle');

Which I've managed to output with the following:

$holds->each(function ($node) {
    echo '<pre>';
    print $node->text();
    echo '</pre>';
});

And results in

<pre>Carrots Like Peas</pre>
<pre>- And Other Fun Facts</pre>

Another problem is that not all the books have subtitles, so I need to avoid combining two titles together. How would I go about combining those two into a single result (or array)?

In my case, I took a roundabout way to get where I wanted to be. I stepped back one level in the DOM to the td tag and grabbed everything and dumped it into the array.

I realized that DomCrawler's documentation had the example code to place the text nodes into an array.

$items_out = $crawler->filter('td.item_info')->each(function (Crawler $node, $i) {
    return $node->text();   
});

I'd tried to avoid capturing the td because author's were also included in those cells. After even more digging, I was able to strip the authors from the array with the following:

foreach ($items_out as &$items) {
    $items = substr($items,0, strpos($items,' - by'));
}

Just took me five days to get it all sorted out. Now onto the next problem!

As per Goutte Documentation, Goutte utilizes the Symfony DomCrawler component. Information on adding content to a DomCrawler object can be found atSymfony DomCrawler - Adding Content
