I am suppoused to create new localized pages from two rss feeds that both have same news in different languages. I am able to create new pages from the first feed, but I have no idea how I could localized those pages with the second feed.
I hope you could give me a hint how this could be done.
I guess you mean creating a second language on an existing page by code:
PageData page = DataFactory.Instance.CreateLanguageBranch(pageLink,new LanguageSelector("en"))
Then make your changes and publish as usual.
