PHP file
$doc = new DOMDocument();
$doc->loadHTMLFile("test.html");
$xpath = new DOMXPath($doc);
$retrieve_data = $xpath->evaluate("//span");
echo $retrieve_data->item(1);
var_dump($retrieve_data->item(1));
var_dump($retrieve_data);
I am trying to use xPath to find the spans and then echo it, but it seems I cannot echo it. I tried dumping it to see if is evaluating properly, and I am not sure what does this output mean:
object(DOMElement)#4 (0) { }
object(DOMNodeList)#7 (0) { }
What does the #4 and #7 mean and what does the parenthesis mean; What is does the syntax mean?
Update:
This is the error I get when I try to echo $retrieve_data; and $retrieve_data->item(1);
Catchable fatal error: Object of class DOMNodeList could not be converted to string
