I need to generate a large XML file inside a Zope application; the file is for backup purposes, so it is stored on the server and can be downloaded later with whatever suitable tool.
The data are taken from a database, and then they are used to create the XML. I assume there will be between 40.000 and 100.000 rows to be dumped.
I thought i could use page template for this purpose, but I'm not sure if it is possible to send the output from a pt to a file, directly.
I fear, this is not a supported usecase: The standard page template implementation writes to a "StringIO" object (thus its internal infrastructure is prepared for incremental output generation) but the file to be written to it not controllable from outside. If your XML is not too complex, I would directly generate it (and not go through a PageTemplate). -- Dieter
