I've followed ET documentation regarding pulling data from RSS feed to email that can be found here:
I've created simple code:
%%[
SET @xmlTemp = ContentAreaByName("my contents\XML\XMLtest")
SET @xml = Replace(@xmlTemp, "content:encoded", "contentencoded")
SET @titles = BuildRowsetFromXML(@xml,"//item/title",1)
]%%
%%=Field(Row(@titles, 1), 'Value'))=%%
It works fine when it's implemented in landing page but generates error when it's used in email. I tried to wrap output into TreatAsContent() but still nothing
