How to retrieve comments from within an XML Document in PHP

Question

I want to extract all comments below a specific node within an XML document, using PHP. I have tried both the SimpleXML and DOMDocument methods, but I keep getting blank out

Answer 1

SimpleXML cannot handle comments, but the DOM extension can. Here's how you can extract all the comments. You just have to adapt the XPath expression to target the node you want.

$doc = new DOMDocument;
$doc->loadXML(
    '
        
        
    '
);

$xpath = new DOMXPath($doc);

foreach ($xpath->query('//comment()') as $comment)
{
    var_dump($comment->textContent);
}
