Question

I have following HTML which I am trying to read from the DOMNodeList when I query a HTML document with xPath in PHP code. This is my query $description = $xpath->query("//div[@class='qsc-html-content']");

I expect that I shall be able to fetch every thing inside 2nd div. Im new to xPath in PHP. The problem is when I try anything like following :

        if(isset($description) && is_object($description)){
        echo "DESCIPTION SET";
        echo $description->tagName;

        //echo $description->getElementsByTagName("p");
        $productInfo['description'] = trim($description->nodeValue);            
    }

I do not get any result.

<div class="product-description ">
<div class="qsc-html-content">
    <p><span class="Apple-style-span" style="background-color: #ffffff; font-family: Verdana, sans-serif;">Farida is a new and upcoming brand in the hookah market which specializes in solid brass hookahs.

    <p>&nbsp;Glass bases are mouth blown and sometimes have air bubbles as evidence of this fact. <span style="font-size: xx-small;">Artisans hand paint each glass base, making every one as unique as the artist.

It also means that sometimes the paint may have a slight smudge, a line may not be perfectly straight, or you may see the artist's brush strokes.</span></p>

</div>

Some one can please guide me where I am wrong. There is another problem where I am trying to fetch list of anchor tags by xPath query and the result is returning only singe anchor.

I had banged my head onto this for last 2 hours. I am exhausted now.

thanks

The result from $xpath->query(...) is a DOMNodeList object. It’s not a single element, so using:

echo $description->tagName;

is wrong. Instead you should iterate the result, like this:

$description = $xpath->query("//div[@class='qsc-html-content']");
foreach ($description as $item) {
    echo $item->tagName . "\n";
}
