DOMXPath var_dump: "(object value omitted)"

Question

$store = curl_exec($ch); // Returns a page of HTML

$doc = new DOMDocument();
$doc->loadHTML($store);
$xpath = new DOMXpath($doc);

Vardump $xpath:

object(DOMXPath)#2 (1) { 
    ["document"] => string(22) "(object value omitted)" 
}

What is wrong here? I'm trying to use xpath on the HTML code to extract info.

object(DOMDocument)#1 (34) {
    ["doctype"]         => string(22) "(object value omitted)" 
    ["implementation"]  => string(22) "(object value omitted)" 
    ["documentElement"] => string(22) "(object value omitted)" 
    ["actualEncoding"]  => string(6) "gb2312" 
    ["encoding"]        => string(6) "gb2312"
    ["xmlEncoding"]     => string(6) "gb2312" 
    ["standalone"]      => bool(true) 
    ...

that's not how xpath works... xpath is a search engine for DOM documents, it's **NOT** the document you loaded. — Marc B, Jul 01 '13 at 04:15

loadHTMLFile requires path of the html file not the content of the html file loadhtmlfile. So your code will be

$doc = new DOMDocument();
$doc->loadHTMLFile("path to html file");
$xpath = new DOMXpath($doc);

Edit

If you want to load from html content use loadhtml

$doc = new DOMDocument();
$doc->loadHTML($store);
$xpath = new DOMXpath($doc);

even with loadHTML , i'm still getting the error. I did a echo on $store. It has html in it – CodeGuru Jul 03 '13 at 10:42
@RainbowHat You will have fetch the result. If you directly `var_dump `, it will always give you same result. – Yogesh Suthar Jul 03 '13 at 10:52

As above has ["textContent"]=> string(2304) , it means the html in it. How do i actually Fetch the result correctly? $elements = $xpath->query("//*[@id='detail']/div[1]/h3/text()"); – CodeGuru Jul 03 '13 at 11:00
@RainbowHat I don't know how this `query("//*[@id='detail']/div[1]/h3/text()");` works, you can look into documentation. – Yogesh Suthar Jul 03 '13 at 11:03
