node import dev and node_import_update installed but not update possible

I've installed the module and I can get through all steps except the last page that is supposed to display progress bar and stats from the process. Nothing is upated, it just shows the initial page again. If I turn off the updater module, it works as expected. Please help! I really need this feature to avoid adding duplicate products when importing. Does anyone know of a better solution than node_import?

Depending on your needs, the Feeds module may be a good choice.

Right now, Node Import Update is experimental, at best.

Thank you, ergonlogic. From your experience, do you know if Feeds has a feature to update nodes that already exist as opposed to creating duplicates? I'm trying to import products which has a required unique identifier SKU. Thanks!

Yes, indeed, Feeds supports updating nodes. The primary challenge that you'll likely face, though, is that there isn't a simple interface for mapping CSV columns to node/CCK fields.

Personally, I'd prefer to use XML, I think it's more legible and makes sense for nodes that have a hierarchal taxonomy(?). Do you know of a current module that supports import/export of XML and allows for updates as well as cron job automation? Thanks! Michelle :)
