How do I iterate through DOM elements in PHP?

dom, php, xml

Solution

Not tested, but what about:

$elements = $dom->getElementsByTagName('foo');
$data = array();
foreach($elements as $node){
    foreach($node->childNodes as $child) {
        $data[] = array($child->nodeName => $child->nodeValue);
    }
}

Problem

I have an XML file loaded into a DOM document, I wish to iterate through all 'foo' tags, getting values from every tag below it. I know I can get values via ``` $element = $dom->getElementsByTagName('foo')->item(0); foreach($element->childNodes as $node){ $data[$node->nodeName] = $node->nodeValue; } ``` However, what I'm trying to do, is from an XML like, ``` <stuff> <foo> <bar></bar> <value/> <pub></pub> </foo> <foo> <bar></bar> <pub></pub> </foo> <foo> <bar></bar> <pub></pub> </foo> </stuff> ``` iterate over every foo tag, and get specific bar or pub, and get values from there. Now, how do I iterate over foo so that I can still access specific child nodes by name?
