Foreaching only the a href data - php

Question

I am using simple_html_dom to gather data from another website and I am wondering how I can do a foreach for only the data as an a element.
$url = 'example.com';
html2 = file_get_html($url);
$download2 = $html2->find('table',1);
$data['ep_table'] = $download2->outertext;
The above code returns the following.
<table style="height: 341px;">
<tbody>
<tr style="height: 31px;">
<td style="height: 31px; width: 26px;">#</td>
<td style="height: 31px; width: 196px;">Song</td>
<td style="text-align: right; height: 31px; width: 82px;">Download</td>
</tr>
<tr style="height: 62px;">
<td style="height: 62px; width: 26px;">1</td>
<td style="height: 62px; width: 196px;">미쳐가지고 (I’m Crazy)</td>
<td style="text-align: right;height: 62px;width: 82px;">
<a href="http://example.com/South-Club-im-crazy/"

How can I do a foreach, which searches only the html of $data['ep_table'] and not the entire page we're parsing for a a element?
I've tried this, with no luck.
foreach($data['ep_table']->find('a') as $track){
print $link = $track->href;
}

Answer 1

You're trying to use find() on plaintext, not a DOM object. You should do this:
$url = 'example.com';
html2 = file_get_html($url);
foreach( $html2->find('table', 1)->find('a') as $track)
{
echo $track->href;
}
It's also worth pointing out that find('table', 1) assumes the target table is the second <table> element in the retrieved markup.
