If you are not so familiar with HTML DOM, check this [link](http://php.net/manual/en/book.dom.php) to learn more...

```php
// Example
echo $html->find("#div1", 0)->children(1)->children(1)->children(2)->id;
// or
echo $html->getElementById("div1")->childNodes(1)->childNodes(1)->childNodes(2)->getAttribute('id');
```
