Answer 1

src is not attribute of a tag, so you need one more step to get inner img tag and then take its attribute
foreach( $nodes as $node ) {
$title = $node->getAttribute('href');
$imgTags = $node->getElementsByTagName('img');
$img = $imgTags->item(0)->getAttribute('src');
echo $title . "," . $img . "<br>";
}

Answer 2

You can try this code.
<?php
$str = '<div id="hot-deals">
<div class="all-deals">
<ul>
<li><a href="http://url1.com">
<img src="http://imagelink1.com"></a>
</li>
<li><a href="http://url2.com">
<img src="http://imagelink2.com"></a>
</li>
<li><a href="http://url3.com">
<img src="http://imagelink3.com"></a>
</li>
</ul>
</div>
</div>';
$nodes = simplexml_import_dom(DOMDocument::loadHTML($str))->xpath('//div[#id="hot-deals"]/div[#class="all-deals"]/ul/li/a');
foreach( $nodes as $node )
{
$title = $node['href'];
$src = $node->img['src'];
echo $title ." " . $src . '<br>';
}
