Generování XML+RSS, n atributy a content type

Werkov

Ahoj, chci generovat XML (konkrétně RSS) pomocí šablon v Nette, ale nějak se mi to nedaří. Poud vynechám onen řádek s contentType [3], tak získám neuzávorkovaný kód [1] (vypisuje chypu Parse error: syntax error, unexpected $end. Pokud tam contentType dám, tak mi zase nefungují n-atributy [2] a výpis výsledku skončí za tím title v obrázu.

Je to nějaká moje chyba nebo Nette?

Ještě poznamenám, že to je šablona pro komponentu, kterou pak vykresluji v šabloně stránky, kde je jen {control rssGenerator}.

Díky.

Tak jsem si s tím hrál a objevil jsem tohle podivné chování. Když tam dám uzavírací tag [1] (s lomítkem), tak se to zblázní a v kompilované šabloně se neudělá endif od toho if($image). Bez uzavíracího tagu [2] se to přeloží v pořádku.

Dělá mi to ve verzi, kterou jsem si právě stáhl (Nette Framework 2.0-dev (revision 539fdec released on 2011–04–13)) i v asi dva měsíce staré (Nette Framework 2.0-dev (revision bb2b723 released on 2011–02–06)).

Myslím, že je to bug. Jestli ne, tak mě nekdo poučte.

n atributy nefungují při content type xml, takže budeš muset psát místo n:if=„…“ normálně {if …}{/if}
