Here is sample php code , run this code with your link as filter as your condition

    Header("Content-type: text/xml"); 
    // get query string params
    $filter = $_GET['filter'];

    $xml = '';

    If ($filter == "city"){
        $xml = $xml . '<continent name="city">';
        $xml = $xml . '<city id="1">Navi Mumbai</city>';
        $xml = $xml . '<city id="2">Thane</city>';
        $xml = $xml . '<city id="3">Pune</city>';
        $xml = $xml . '</continent>';
    }else If ($filter == "country"){
        $xml = $xml . '<continent name="country">';
        $xml = $xml . '<country id="100">India</country>';
        $xml = $xml . '</continent>';
    }else If ($filter == "state"){
        $xml = $xml . '<continent name="state">';
        $xml = $xml . '<state id="300">Maharastra</state>';
        $xml = $xml . '</continent>';
    }else{
        $xml = $xml . '<continent name="none">';
        $xml = $xml . '<country id="0">no result found</country>';
