Add condtions to element

[neverender24]

How do I filter which element is being processed?

for example, I have mutiple classes:
$sels = "h2, .pnlDescription, .address";

I want to have a condition with the ".address" since I want to alter the text within it.

if(".address" == "somestring")
{
----code---
}

Where and how can I achieve this one?

I would go the other way:

$h2 = $doc->find('h2');
$desc = $doc->find('.pnlDescription');
$address = $doc->find('.address');
// ... do something with these

There are still some other options, but I think they are less performant:

$sels = $doc->find('h2, .pnlDescription, .address');
foreach($sels as $e) switch(true) {
    case $el->hasClass('address'): {
        // ...
    } break;
    case $el->nodeName == 'h2': {
        // ...
    } break;
}

I would like to have ->is($selector) method, but have never had the need for it.

Thanks for feedback that's all I need.
