Freemind map xml parsing get last childs with simplexml php

I am having an issue when parsing with SimpleXML an XML file what actually freemind map.

XML example:

<map version="1.0.1">
<node TEXT="str_1">
    <node TEXT="str_2">
        <node TEXT="str_3"/>
        <node TEXT="str_4">
            <node TEXT="str_5">
                <node TEXT="str_6"/>
            </node>
            <node TEXT="$ str_7"/>
            <node TEXT="str_8"/>
            <node TEXT="$ str_9"/>
        </node>
    </node>
    <node TEXT="str_10"/>
    <node TEXT="str_11"/>
    <node TEXT="$ str_12"/>
</node>
</map>

And with folowing code i can get all childs:

function print_node_info($father, $node)
{

        $output_xml = $node['TEXT'].' - Son of - '.$father.'</br>';

        echo $output_xml;

            // $file = 'output.xml';
            // // Open the file to get existing content
            // $output_xml .= file_get_contents($file);
            // // Write the contents back to the file
            // file_put_contents($file, $output_xml);

                //echo 'father: ' . $father.'<br>';
                //echo 'node: ' . $node['TEXT'].'<br><br>';
                foreach ($node->children() as $childe_node)
                //foreach $xml->xpath("//node[last()]")[0]->attributes() as $Id)
                //foreach ($node as $childe_node) 
                {
                    $GLOBALS['grandfather'] = $father;
                    print_node_info($node['TEXT'], $childe_node);
                }   
}

$xml = simplexml_load_file('1.xml');

foreach ($xml->children() as $first_node) {
print_node_info("top_name", $first_node);
}

What i am trying to get is only all last children's TEXT value, actually nodes which not contains children's.

Any help would be appreciated

Thanks in advance!

You can do this rather easily using SimpleXMLElement::xpath and array_map.

$values = array_map(function($node) {
    return (string) $node['TEXT'];
}, $xml->xpath('//node[not(node)]'));

You can see that first we get an array of node that do not have children, then we transform each of those nodes into a string containing the node's TEXT attribute.
