Try something like this:

$objectX = "2"; // You get this value with $_POST or $_GET ...
$xmlFileName = 'my.xml'; // You're XML file

$xmlFile = file_get_contents($xmlFileName); // Saving the XML contents in a variable
$objects = new SimpleXMLElement($xmlFile);

$objectX = "object".$objectX; // The object name
$objects->$objectX->value++; // Incrementing the value
$objects->asXML($xmlFileName); // Saving the XML

echo $objects->$objectX->value; // echo the value

You have to add <objects></objects> to your XML file:

<?xml version="1.0" encoding="UTF-8"?>
<objects>
    <object1>
        <value>10</value>
    </object1>
    <object2>
        <value>6</value>
    </object2>
</objects>
