Use SimpleXML:

$xml = simplexml_load_file($yourXMLPath);

//Loop for element...
foreach ($xml->STRING as $string) {
    //Update value for <STRING id="Name">...
    if($string->attributes()->id == 'Name'){
        $xml->STRING = 'XYZ';
    }

    //Update value for <STRING id="Name">...
    if($string->attributes()->id == 'ISBN'){
        $xml->STRING = '7777';
    }
}

// save the updated document
$xml->asXML('newXML.xml');

No error in code but it did not update value as expected and one more thing code should handle( BookID should be place before xmlns attribute) – Prakash Dec 29 '15 at 12:05
check with print_r($xml); xml object value. – AddWeb Solution Pvt Ltd Dec 29 '15 at 12:06
Thank you for reply,but print_r printing existing value not updated one. – Prakash Dec 29 '15 at 12:27
Ok, means issue with condition. Can you please check `print_r($xml->STRING);` – AddWeb Solution Pvt Ltd Dec 29 '15 at 12:29

Sorry my mistake, use $string->attributes()->id not $string->attributes()->Id. Check after take this change... – AddWeb Solution Pvt Ltd Dec 29 '15 at 12:50
it gives error "Warning: main(): Cannot assign to an array of nodes (duplicate subnodes or attr detected) in test.php line 8" line 8 has code $xml->STRING = 'XYZ'; – Prakash Dec 29 '15 at 12:59
