Simple HTML Dom: How to remove elements?

I think you have some difficulties because you forgot to save(dump the internal DOM tree back into string).

Try this:

$html = file_get_html("http://example.com");

foreach($html ->find('img') as $item) {
    $item->outertext = '';
    }

$html->save();

echo $html;

I could not figure out where to put the function so I just put the following directly in my code:

$html->load($html->save());

It basically locks changes made in the for loop back into the html per above.

when you only delete the outer text you delete the HTML content itself, but if you perform another find on the same elements it will appear in the result. the reason is that the simple HTML DOM object still has it's internal structure of the element, only without its actual content. what you need to do in order to really delete the element is simply reload the HTML as string to the same variable. this way the object will be recreated without the deleted content, and the simple HTML DOM object will be built without it.

here is an example function:

public function removeNode($selector)
{
    foreach ($this->find($selector) as $node)
    {
        $node->outertext = '';
    }

    $this->load($this->save());        
}

put this function inside the simple_html_dom class and you're good.

There is no dedicated methods for removing elements. You just find all the img elements and then do

$e->outertext = '';
