This example uses get_elements_by_tagname() and child_nodes() to output the contents of the xml file. The sample xml file and php code are below.

<?xml version="1.0" encoding="iso-8859-1"?>
    <meaning>used to express a greeting</meaning>
    <example>Hello World!</example>

= "/some/dir/dictionary.xml";
    if (!
$dom = domxml_open_file($xml_path)) {
//the above requires absolube path
exit("Could not access the XML source.");
$root = $dom->document_element(); //obtain the root
$array_entry = $root->get_elements_by_tagname("entry"); //gets all <entry> DomElems
foreach ($array_entry as $entry_dom_elem) {   
$childnodes = $entry_dom_elem->child_nodes();
        foreach (
$childnodes as $child) { //cycle thru <word>, <meaning>, <example>
echo "node name: ".$child->tagname() . "; contains: " . $child->get_content()."<br>";
The above code outputs:
node name: word; contains: Hello
node name: meaning; contains: used to express a greeting
node name: example; contains: Hello World!

Function get_elements_by_tagname() is only defined for the DocumentRoot-Element rather than for any DocumentElement.

if you want to search for tagnames with namespaces, do it the following way:
(it's a work around, not a really proper solution..)

$dom = domxml_open_mem($xmlval);
$nodes = $dom->get_elements_by_tagname("yns:tagname",$ctx);
