检索标签内的所有信息：DOMNODE

Question

I have a script in which I have no control over the HTML and can only modify the basic CSS. I just wanted to know if it is possible to cut all the information from < script> until its closing </ script> without distinguishing between the elements inside?

Example:

<script src='http://localhost/[...]/assets/js/frontend.min.js?ver=3.5.3'
    id='elementor-frontend-js'></script>

So for example here I would like to retrieve the whole line in string form to store it in an array.

    $document = new DOMDocument();
    libxml_use_internal_errors(true);

    $document->loadHTML($content);
    libxml_use_internal_errors(false);

    // An empty array to store all the 'srcs'
    $scripts_array = [];

    // Store every script's source inside the array
    foreach ($document->getElementsByTagName('script') as $script) {
        if ($script->hasAttribute('src')) {
            $scripts_array[] = $script->getAttribute('src');
        }
    }

So here is a piece of my code, for now I manage to retrieve the loaded document, browse the scripts but I only pull the "src" attribute; but I want to retrieve all the content without distinction.

Thank you for your answers: :)

Answer 1

You are getting only the src attribute value, because that's all you are asking for in $script->getAttribute('src') . Replace your foreach with:

$xpath = new DomXPath($document);
$attribs = $xpath ->query("//script/@*");

foreach ($attribs as $attrib) {     
            $scripts_array[] = $attrib->nodeValue ;            
    }

and see if it works.

Answer 2

first of all thank you for your answer, I tried. and I don't get what I want: When I do a query I get this:

 "more_info": [
    "http://localhost:8888/Sadem/wordpress/wp-content/plugins/elementor/assets/lib/font-awesome/js/v4-shims.min.js?ver=3.5.5",
    "font-awesome-4-shim-js",
     ...and more
]

What I was looking for was having the complete line like this: "more_info": [ "http://localhost/.../assets/lib/font-awesome/js/v4-shims.min.js", "font-awesome-4-shim-js", ...and more ]

What I was looking for was having the complete line like this:

"more_info": [
    "<link rel='stylesheet' href='http://localhost/.../assets/lib/font- 
     awesome/js/v4-shims.min.js' id='font-awesome-4-shim-js'/>",
     ...and more
] 

But I thank you again for your help, so few people want to help me....
