extract untagged elements with symfony dom crawler

How to extract untagged elements with symfony dom crawler. For example in the sample html below I want to extract Hello World.

<strong>title</strong>Hello World<strong>Sub-Title</strong><div>This is just stuff</div>

Answer

You could do this easily with PHP DOM 😉

$dom = new DOMDocument();
$dom->loadHTML('<strong>title</strong>Hello World<strong>Sub-Title</strong><div>This is just stuff</div>');
$xpath = new DOMXPath($dom);
// use the fact that PHP DOM wraps everything into the body and get the text()
$entries = $xpath->query('//body/text()');
foreach ($entries as $entry) {
    echo $entry->nodeValue;
}
