Aplicatia
afiseazaPictori contine alaturi de pictori.xml si pictoriXSLT.xsl fisierele pictori.html,
functii.js si pictori.php. Fisierele amintite vor fi incluse in subdirectorul afiseazaPictori al directorului

Fisierul functii.js contine definitiile functiilor JavaScript utilizate in aplicatie: afiseazaPictori() trateazaCererea( arataDiv() si ascundeDiv(). In continuare sunt prezentate definitiile primelor doua functii:
// Functia de trimitere a cererii asincrone catre server
var cerere;
function afiseazaPictori()
// Functia pentru tratarea evenimentelor de transmisie asincrona
function trateazaCererea()
else
Fisierul pictori.php prin a carui executie este generat raspunsul trimis clientului de catre server are urmatorul continut:
<?php
// Este incarcat documentul XML
$xml = new DOMDocument;
$xml->load('pictori.xml');
// Este incarcat documentul XSL
$xsl = new DOMDocument;
$xsl->load('pictoriXSLT.xsl');
// Se creeaza un procesor
$procesor = new XSLTProcessor;
// Se includ regulile xsl definite in pictori_transf.xsl
$procesor->importStyleSheet($xsl);
// Se realizeaza transformarea XSLT si se afiseaza rezultatul
echo $procesor->transformToXML($xml);
?>
