Zadanie

Skript načíta RSS alebo Atom XML a pomocou objektu SimpleXML ho prevedie do HTML kódu, ktorý odovzdá na výstupe.

Riešenie

Použijeme Typo3 objekt USER (include PHP script).

Typoscript

includeLibs.rss = fileadmin/sitename/inc/parser_rss.inc 
temp.parserRss = USER
temp.parserRss {
  userFunc = user_parser->parser
  wrap = <div class="parserBox"><h4 class="headerColor headerYellow">Tehotenstvo</h4><div class="parserBoxIn hColorYellow">|</div></div>
  # Setup for RSS
  # url = sitename.sk/fileadmin/sitename/temp/rss.xml
  # type =
  # Setup for Atom
  url = sitename.sk/fileadmin/sitename/temp/atom.xml
  type = atom
}
