Finding within parsed div [Simple HTML DOM] - php

Question

I want to fetch the <a> link within the div glance_details. I can't really make it work. Don't worry about including and the url and things, that is all correct.
$redirect = $url;
$html3 = file_get_html($redirect);
foreach($html3->find('div.glance_details') as $element3) {
$html3->find('a',0)->outertext;
}
with
$redirect = $url;
$html3 = file_get_html($redirect);
foreach($html3->find('div.glance_details') as $element3) {
$knaoss = $element3->plaintext;
echo $knaoss;
}
I can fetch the plain text content of the div, but what I want is the anchor (a) that will be within the div.
This is similar to what I receive in $knaoss if I remove the ->plaintext:
<div class="glance_details">
<a href="http://www.example.com/">
<img src="http://www.example.com/img.png">
</a>
"This is a description of the example"
</div>
Though all I want from it is:
http://www.example.com/

Answer 2

The solution was simple. Only had to change:
$redirect = $url;
$html3 = file_get_html($redirect);
foreach($html3->find('div.glance_details') as $element3) {
$knaoss = $element3->plaintext;
}
to
$redirect = $url;
$html3 = file_get_html($redirect);
foreach($html3->find('div.glance_details > a') as $element3) {
$knaoss = $element3->href;
}
to find the href within div.glance_details. Problem was I used words like "url" and "link" instead of href, and could therefor not make it work.
