Remove parent element, keep all inner children in DOMDocument with saveHTML

Question

I\'m manipulating a short HTML snippet with XPath; when I output the changed snippet back with $doc->saveHTML(), DOCTYPE gets added, and HTML / BODY

Answer 1

Here how I've done it:

-- Quick helper function that gives you HTML contents for specific DOM element

function nodeContent($n, $outer=false) {
   $d = new DOMDocument('1.0');
   $b = $d->importNode($n->cloneNode(true),true);
   $d->appendChild($b); $h = $d->saveHTML();
   // remove outter tags
   if (!$outer) $h = substr($h,strpos($h,'>')+1,-(strlen($n->nodeName)+4));
   return $h;
}

-- Find body node in your doc and get its contents

$query = $xpath->query("//body")->item(0);
if($query)
{
    echo nodeContent($query);
}

UPDATE 1:

Some extra info: Since PHP/5.3.6, DOMDocument->saveHTML() accepts an optional DOMNode parameter similarly to DOMDocument->saveXML(). You can do

$xpath = new DOMXPath($doc);
$query = $xpath->query("//body")->item(0);
echo $doc->saveHTML($query);

for others, the helper function will help
