Question

I am loading HTML into DOM and then querying it using XPath in PHP. My current problem is how do I find out how many matches have been made, and once that is ascertained, how do I access them?

I currently have this dirty solution:

$i = 0;  
foreach($nodes as $node) {  
    echo $dom->savexml($nodes->item($i));  
    $i++;
}

Is there a cleaner solution to find the number of nodes, I have tried count(), but that does not work.

You haven’t posted any code related to $nodes so I assume you are using DOMXPath and query(), or at the very least, you have a DOMNodeList.
DOMXPath::query() returns a DOMNodeList, which has a length member. You can access it via (given your code):

$nodes->length
