Simple-html-dom list ordering nested without class - php

Question

i am literally stuck with getting these ul/li elements in one row.
Only first li has class, others are in another ul but without class or id. i tried multiple searches and loops, but can't get it right.
Below results returns too many rows where elements don't fit together.
Can someone help me?
idealy the result from below example would be:
'part', 'desc', 'qty'
'106128-001','LBL, BLNK,THERMAL PRINT','1'
'106128-004','LBL, BLNK THERMAL,RECT 2.40x4','1'
HTML example
<div id='tab1' class="section tab" data-position="auto" style="max-height:none;">
<ul class="links">
<li id="innertab1">106128-001</li>
</ul>
<ul id="combom0" class="tab1 cols2 compare">
<li style="border: none;">
<div>
<ul>
<li><strong>Description: </strong>LBL, BLNK,THERMAL PRINT</li>
<li><strong>Qty: </strong>1</li>
</ul>
</div>
</li>
</ul>
<ul class="links">
<li id="innertab1">106128-004</li>
</ul>
<ul id="combom1" class="tab1 cols2 compare">
<li style="border: none;">
<div>
<ul>
<li><strong>Description: </strong>LBL, BLNK THERMAL,RECT 2.40x4</li>
<li><strong>Qty: </strong>1</li>
</ul>
</div>
</li>
</ul>
My poor attempt with trying to count rows:
$search = $html->find('div[id=tab1]',0);
$i=0;
$alles=array();
foreach ($search->find('* li') as $test){
if(!empty($test->innertext)){
if($i>3){$i=0;}
$i++;
if($i==1){
echo $alles_li['part'] = strip_tags($test->innertext);
}
if($i==2){
// don't need this, bad stripping
strip_tags($test->innertext);
}
if($i==3){
$alles_li['desc'] = strip_tags($test->innertext);
}
if($i==4){
$alles_li['qty'] = strip_tags($test->innertext);
}
}
// if less than 3 elements don't add
if(count($alles_li)==3){
$alles[]=$alles_li;
}
}
