Hi fernando,
i recently constructed a navigation bar with zope. now i would like to include a functionality to switch languages. when clicking on a "spanish" button, the folder ids that are displayed shall be replaced by the values of a spanish attribute - the corresponding spanish description for the link. depending on whether spanish content exists for this link either a spanish or english default document shall be displayed in the right part of the window. for carrying out this if-query i need to look dynamically - always when the button is clicked - into the folder level, one level below the context and search the "spanish_default". so, please, what is the command (dtml or python) for "starting a search" for a document that is situated in a folder (which is not known by name, because it changes) one level below the current context folder. (like <dtml-if ../spanish_default> do... ).
There are several Zope products for internationalization/localization: Localizer, ZBabel, vary tag, etc. I think this is what you are searching for and its less expensive to use them than to code everything by yourself. You can get Localizer from http://sourceforge.net/projects/lleu If you nevertheless don't want to use an external Product: To check the existance of an object in the current folder whose name is stored in the string objName use: <dtml-if "_.getitem(objName)"> To check other folders you could either use getitem and the dtml-with tag or the following: <dtml-if "_.hasattr(folderObj,objName)"> Bye, Eric
