$xpath = new \DOMXPath($dom);
$nodelist = $xpath->query('//div/p/img');
foreach($nodelist as $k=>$v){
$title1 = $v->parentNode->previousSibling->textContent;
}
I want to retrieve every text inside h1 tag, but previousSibling attribute seems to be not working, it returns a node without tagname attribute and its previousSibling attribute is "(object value omitted)"
My path must be followed as img->p->previous h1 , since not every p tag has its own h1 tag in my case.
Thank you !

Based on your markup above, note that the immediate sibling of <p> is actually a new line character \n.
As an alternative, you could check for that preceding sibling first and check whether it's an <h1> tag, if it is, then get its ->nodeValue:
$nodelist = $xpath->query('//div/p/img');
foreach($nodelist as $k=>$v) {
// $previousSibling = $
$prev = $xpath->evaluate('./preceding-sibling::*[1]', $v->parentNode);
if($prev->length > 0 && $prev->item(0)->tagName === 'h1') {
echo $prev->item(0)->nodeValue, '<br/>';
}
}
