使用simple_html_dom获取没有childNodes且没有格式的td

I'm trying, with simple_html_dom to get the value of a td, without the child it can have.

<td>223 <span class="added-time">ADDED September 14, 2015</span> </td>

Is the code I'm extracting.

$html = file_get_html($row['address']);
$numberviews = $html->find('td', 5);
$numberviews->childNodes(0)->outertext = '';
echo $numberviews->innertext;

The problem is that this code keeps the text format of the page I'm scraping from.

How can I kill the text format & get rid of the childNodes at the same time?

thanks
