How interpret Simple XML to HTML with PHP?

I get response from the server in Simple XML, but I want get to my page only data I need and show this data in html tags. How I can do it?

My request code:

    include "TopSdk.php";
    date_default_timezone_set('Asia/Shanghai'); 
    $c = new TopClient; 
    $c->appkey = '*******';
    $c->secretKey = '***************';
    $req = new AliexpressAffiliateProductQueryRequest; 
    $req->setAppSignature("1111"); 
    $req->setFields("sale_price"); 
    $req->setKeywords("car"); 
    $req->setMaxSalePrice(300); 
    $req->setMinSalePrice(150); 
    $req->setPageNo(1); 
    $req->setPageSize(2); 
    $req->setSort("SALE_PRICE_ASC"); 
    $req->setTargetCurrency("USD"); 
    $req->setTargetLanguage("en"); 
    $req->setTrackingId("trackID");
    echo "<pre>";
    var_dump($c->execute($req));
    echo "</pre>";

Server response in SXML:
