php how to find all child nodes of a given node

My XML input is like this: 

<Configuaration>
    <Allowances>
        <payhead>
            <code>123</code>
            <name_en>Basic</name_en>
            <source>anything</source>
        </payhead>
    </Allowances>
    <Deductions>
        <payhead>
            <code>444</code>
            <name_en>House Rent</name_en>
            <source>anything</source>
        </payhead>
    </Deductions>
</Configuaration>

What I want is like, in my php function I will give 2 parameters. 1st one is the input xml and 2nd one is the searchTag (all child nodes under this tag should return).

my php function: 

<?php
class myXMLUtil
{
    public static function getValue($inputXML, $searchTag)
    {
        $dom = new DOMDocument;
        $dom->loadXML($inputXML);
        $childs = $dom->getElementsByTagName($searchTag);
        foreach ($childs as $child) {
            echo '<'.$child->nodeName.'>'.$child->nodeValue.'</'.$child->nodeName.'>'.PHP_EOL;
        }
    }
}
?>

so if i put the_xml_string and 'payhead' as the function parameter then it should return 

<payhead>  
    <code>123</code>  
    <name_en>Basic</name_en>  
    <source>anything</source>  
</payhead>  
<payhead>  
    <code>123</code>  
    <name_en>Basic</name_en>  
    <source>anything</source>  
</payhead>

but instead i get 

<payhead>123Basicanything</payhead>  
<payhead>444House Rentanything</payhead>

I dont understand it. Can anybody help? If there is something wrong in my code then how can I achieve it? TIA.

It looks like you need this function:

class myXMLUtil
{
    public static function getValue($inputXML, $searchTag)
    {
        $dom = new DOMDocument;
        $dom->loadXML($inputXML);
        $foundElements = $dom->getElementsByTagName($searchTag);
        foreach ($foundElements as $foundElement) {
            echo $foundElement->ownerDocument->saveXML($foundElement);
        }
    }
}

You can run locally this code:

<?php
$xml = <<<EOF
<Configuaration>
<Allowances>
    <payhead>
        <code>123</code>
        <name_en>Basic</name_en>
        <source>anything</source>
    </payhead>
</Allowances>
<Deductions>
    <payhead>
        <code>444</code>
        <name_en>House Rent</name_en>
        <source>anything</source>
    </payhead>
</Deductions>
</Configuaration>
EOF;
class myXMLUtil
{
    public static function getValue($inputXML, $searchTag)
    {
        $dom = new DOMDocument;
        $dom->loadXML($inputXML);
        $foundElements = $dom->getElementsByTagName($searchTag);
                foreach ($foundElements as $foundElement) {
                        echo $foundElement->ownerDocument->saveXML($foundElement);
                }
    }
}
myXMLUtil::getValue($xml, 'payhead');
?>

And it will return

<payhead>
    <code>123</code>
    <name_en>Basic</name_en>
    <source>anything</source>
</payhead><payhead>
    <code>444</code>
    <name_en>House Rent</name_en>
    <source>anything</source>
</payhead>
