Cannot get xml element attribute value from a recursive function in PHP?

Question

I cannot get the attribute value of the xml element becaue everytime i click the link there is no value in id= but when view my xml there is a attribute value, why is this happening am i missing something?

Here is my PHP code:

 <?php
function parse_recursive(SimpleXMLElement $element, $level = 0)
{
    $indent = str_repeat('', $level); 

    $value = trim((string) $element); 
    $children = $element->children(); 
    $attributes = $element->attributes();

    echo '<ul>';
    if(count($children) == 0 && !empty($value))
    {   
        if($element->getName() == 'GroupName'){
            echo '<li><a href="http://localhost:8080/test/test.php?id=';
            if(count($attributes) > 0)
            {
                foreach($attributes as $attribute)
                {
                    if($attribute->getName() == 'Id'){
                        echo $attribute;
                    }
                }
            }
            echo '">'.$element.'</a></li>';
        }
    }   

    if(count($children))
    {
        foreach($children as $child)
        {
            parse_recursive($child, $level+1);
        }
    }
    echo '</ul>';
}

$xml = new SimpleXMLElement('main.xml', null, true);
parse_recursive($xml);
?>

Here is my xml structure:

It appears that your code will only output anything for GroupName elements:

if($element->getName() == 'GroupName'){

and it will only output the Id attributes of GroupName elements.

The single GroupName in your source XML doesn't have an Id attribute.

I'm not sure. It just depends on what you are trying to do. Could you provide a sample of what the expected result is?
