How to find an element by attribute using QueryPath

Question

I need to find all tables with width=230

So far I have:

foreach($qp->top('table')->get() as $table) {
    $width = $table->attr('width');
}

But I get a "Call to undefined method DOMElement::attr()" error.

Answer 1

It seems, $table is a DOMElement, so probably you can do

$width = $table->getAttribute('width);

Answer 2

Try something like

$table->find('[width="230"]');
