Question

I’ve looked through the other Stackoverflow questions on this topic and none of the solutions provided there seem to work for me.

I have an html page (scraped with file_get_contents()) and in that html is a div with an id of “main” – I need to get the contents of that div with PHP’s DOMDocument, or something similiar. For this situation I can’t use the SimpleHTMLDom parser, which complicates things a bit.

Answer 1

DOMDocument + XPath variation:

$xml = new DOMDocument();
$xml->loadHtml($temp);
$xpath = new DOMXPath($xml);

$html = '';
foreach ($xpath->query('//div[@id="main"]/*') as $node)
{
    $html .= $xml->saveXML($node);
}

If you’re looking for innerHTML() (PHP DOMDocument Reference Question) – instead of innerXML() as in this answer – the xpath related variant is given in this answer.

Here the adoption with the changes underlined:

$html = '';
foreach ($xpath->query('//div[@id="main"]/node()') as $node)
                                          ######
{
    $html .= $xml->saveHTML($node);
                       ####
}
