Aby sme mohli vypracovat vystup kanalu budeme musiet skontrolovat ci PHP obsahuje extension XSL. Dalej budeme potrebovat jeden XML subor, ktory bude mat zachovanu strukturu pre RSS (jeden taky si uvedieme v priklade). Dalej si budeme musiet vytvorit XSL subor, ktory bude pre dany XML subor fungovat ako styl. Priklad XML (rss struktura) suboru: <rss version='2.0'> <channel> <title>Titulok</title> <link>http://localhost/tpl/</link> <description>rss kanal pre Titulok</description> <language>sk</language> <lastBuildDate>Fri, 03 Feb 2006 14:36:25 GMT</lastBuildDate> <image> <title>obrazok</title> <url>http://localhost/tpl/template.jpg</url> <link>http://localhost/tpl/</link> </image> <item> <title>Clanok 3</title> <link>http://localhost/tpl/clanok-3/</link> <description> Lorem ipsum dolor sit amet consectetuer id nibh Vestibulum nibh at.

Subory je mozne viazat aj cez zapis <?xml-stylesheet... ale nepouzijeme ho, pretoze tento priklad zahrnuje aj pouzite jazyka PHP. <?php $xml = new DOMDocument; $xml->load('template.xml'); $xsl = new DOMDocument; $xsl->load('template.xsl'); $convert = new XSLTProcessor; $convert->importStyleSheet($xsl); echo $convert->transformToXML($xml); ?> Vysledok si mozete prezriet na tejto adrese. Vyhodou takehoto stylovania je funkcnost zobrazenia v kazdom prehliadaci. Hlavny ciel prikladu bol kladeny hlavne na princip funkcnosti technologie XSLT. XML struktura RSS bola uvedena len ako priklad vyuzitia. Najlepsi manual na XSLT najdete na adrese: http://www.kosek.cz/xml/xslt/
