Using PHP DOM document, to select HTML element by its class and get its text

Question

I trying to get text from div where class = \'review-text\', by using PHP\'s DOM element with following HTML (same structure) and following code.

Answer 1

Expanding on Frak Houweling answer, it is also possible to use DomXpath to search within a specific DomNode. This can be acheived by passing the contextNode as a second argument to DomXpath->query method:

$dom = new DOMDocument;
$dom->loadHTML ($html);
$xpath = new DOMXPath ($dom);

foreach ($xpath->query ("//section[@class='page single-review']") as $section)
{
    // search for sub nodes inside each element
    foreach ($xpath->query (".//div[@class='review-text']", $section) as $review)
    {
        echo $review->nodeValue;
    }
}

Note that when searching inside nodes you need to use relative paths by adding a dot . at the beginning of the expression:

"//div[@class='review-text']" // absolute path, search starts from the root element
".//div[@class='review-text']" // relative path, search starts from the provided contextNode
