Hướng dẫn dùng xpath wildcard trong PHP

I want to retrieve all the content in a div element in HTML. I am using PHP and XPath to do it. Here is the query:

$doc = new DOMDocument(); $doc->loadHTMLFile($uri); $xpath= new DOMXPath($doc); $text_content = $xpath->query("/html/body/div[5]/div[1]/div[1]/div[1]/div[2]/div[5]/*");

I used wild card "*" to retrieve all elements (normal text, div, img, p etc.) under this div(div[5]), but when I printed the $text_content, I found out that it only stored all the div elements.

What is the correct way to do so?

Thanks in advance.
