Question

I’m using jquery to add rel=brochure using $('.imageOuter a').attr('rel', 'brochure') this works as expected.

However, I want to grab the link that has rel as brochure. I’m trying to do this with loadHTML, as below:

function getBrochureLink() {
    $doc = new DOMDocument();
    $doc->loadHTML($file);
    $area = $doc->getElementsByTagName('body')->item(0);
    $links = $area->getElementsByTagName("link");
    foreach($links as $l) {
    if($l->getAttribute("rel") == "brochure") {
            $brochureLink = $l->getAttribute("href");
    }
    }   
}

Sadly $brochureLink is empty and not grabbing it.

Your issue is that the attr is set via Javascript. When you retrieved the page’s contents via loadHTML, the JS was not executed, so you can’t find the matching link.

You’ll have to either run the JS on the server side, put the attr into the DOM directly without JS, or find another architecture for whatever you’re attempting to accomplish.
