PHP to get html source, then parse values within certain DIV tags

Question

I can get the source code fine, but I now want to be able to get the data from within a specific div:

$html = file_get_contents('http://www.website.com');

say $html contains:

<div class="productData">
   <div class="productDescription">Here is the product description</div>
   <div class="productPrice">1.99</div>
</div>

I want to be able to return the data within , and do this for all occurrences?

Thank you.

Use the DOMDocument class, combined with DOMXPath, something like this:

$url = 'http://www.website.com/';
$dom = new DOMDocument();
$dom->load($url);
$xpath = new DOMXPath($dom);
$nodes = $xpath->query("//*[contains(@class, 'productData')]");
foreach ($nodes as $node) {
    // do something
}

either do this or use preg_match function for matching the strings and manipulating

I did try something along these lines, but I get this: Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: Unexpected end tag : head in Entity

What if you use the revised code (change $url to whatever you want to use)

I get: Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: htmlParseEntityRef: expecting ';' in Entity Could this be anything to do with the page containing javascript?
