Exclude particular class name in CSS selector using html dom - html

Question

I want to import only texts that contain only class="item-name"
Not and class="item-name active"
How do you think I could apply the import?
The HTML code is :
<li class="list-item" itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem">
<a class="item" itemscope itemtype="http://schema.org/Thing" itemprop="item" href="/">
<span class="item-name" itemprop="name">Category</span>
</a>
</li>
<li class="list-item" itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem">
<a class="item" itemscope itemtype="http://schema.org/Thing" itemprop="item" href="/outlet">
<span class="item-name" itemprop="name">Category 1</span>
</a>
</li>
<li class="list-item" itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem">
<a class="item" itemscope itemtype="http://schema.org/Thing" itemprop="item" href="/outlet/fragrance">
<span class="item-name" itemprop="name">Category 2</span>
</a>
</li>
<li class="list-item" itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem">
<span class="active-item" itemscope itemtype="http://schema.org/Thing" itemprop="item">
<span class="item-name active" itemprop="name">Title</span>
</span>
</li>
My php code :
if ($html !== false) {
$prod['id']=$html->find('span.code',0)->plaintext;
$j=0;
while (isset($html->find('span.item-name',$j)->plaintext)) {
$cats[]=str_replace(['.',';'],' ',html_entity_decode($html->find('span.item-name',$j)->plaintext));
$j++;
}
$prod['category']=implode(', ',$cats);
unset($cats);
}
UPDATE I fix
if ($html !== false) {
$prod['id']=$html->find('span.code',0)->plaintext;
$j=0;
while (isset($html->find('a.item',$j)->plaintext)) {
$cats[]=str_replace([' ','&#39',';'],' ',html_entity_decode($html->find('a.item',$j)->plaintext));
$new = preg_replace(['(\s+)u', '(^\s|\s$)u'], [' ', ''], $cats);
$j++;
}
$prod['category']=implode(', ',$new);
unset($new);
}
