Google Base - Show stock status and not quantity

Hi,

I have a minor problem. I have a modified Google Base feed and it is showing the stock quantity (for example for Apples it shows number 6 and not "In stock" or "Out of Stock"). On my website it shows "In stock" and "Out of stock".

I don't want to show the actual quantity in my google base feed, but only the stock status. How can i change that? Now i have this line:

$output .= '<g:quantity>' . $product['quantity'] . '</g:quantity>';

$output .= '<g:quantity>' . ($product['quantity']>0?'In stock':'Out of stock') . '</g:quantity>';

Thanks, I will try it out.

I have one more question - how do I manually generate the feed. And how do I configure the automatic generation of the feed weekly or daily? I don't find any scheduler. Is it possible to run it with cron? Which command?

After you set-up the feed in Google Merchant, you will see a schedule link

As the feed is dynamic, it is created when called by Google
