Display all nodes in a xml

Question

This is my xml structure:

<?xml version="1.0"?>
    <Module_Files>
        <Category name="test1">
            <file lang="fr">
                <title>Menu</title>
                <description>Menu list</description>
                <path>menu.pdf</path>
            </file>
        </Category>
        <Category name="test2">
            <file lang="fr">
                <title>Spa</title>
                <description>Services offered in our Spa</description>
                <path>spa.pdf</path>
            </file>
            <file lang="en">
                <title>Gym</title>
                <description>rate</description>
                <path>gym.pdf</path>
            </file>

        </Category>
    </Module_Files>

I want to get for each category <Category> all files <file> . but I only managed to get the first file. I want to display like this (I take test2 Category for the example):

title : Spa, description : Services offered in our Spa, path: spa.pdf

title : Gym, description : rate, path : gym.pdf

This is my code :

 $categoryConfig = $xmlFile->xpath("//Category[@name='" . $categorySelected . "']/config");

 foreach ($categoryConfig as $key => $value) 
 {  
    $rightPanel .= $key . ":" . $value;   
 }

And this is what I get with this code:

0 : 1:

var_dump($categoryConfig) =

array(2) { 
    [0]=> object(SimpleXMLElement)#26 (4) 
        { ["@attributes"]=> array(1) { ["lang"]=> string(2) "fr" } 
        ["title"]=> string(3) "Spa" ["description"]=> string(35) "Services offered in our Spa" ["path"]=> string(7) "spa.pdf" } 

    [1]=> object(SimpleXMLElement)#27 (4) 
        { ["@attributes"]=> array(1) { ["lang"]=> string(2) "en" } 
        ["title"]=> string(14) "Gym" ["description"]=> string(29) "Rate" ["path"]=> string(18) "gym.pdf" } 
    }

Answer 1

Nested loops with the children() -method will do it:

$xml = simplexml_load_string($x); // assume XML in $x

$catname = "test2";
// select all <file> under <category name='test2'>
$files = $xml->xpath("/*/Category[@name='$catname']/file");

foreach ($files as $file) {
    foreach ($file->children() as $key => $value) 
        echo $key . ': ' . $value . PHP_EOL;
    echo PHP_EOL;
}        

As ThW's comment points out, your xpath expression does not match, as there is no <config> in the xml. I adjusted it to <file> here.
