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. Of course, this is a problem which can be easily solved.If you're using Zope 2.10 or higher, you can either use the "native" ZPT implementation from Zope 3 (see zope.pagetemplate module) or you use the Zope 2 implementation (which is basically only a wrapper around the Z3 implementation). In this case you might look at the unittests in testZopePageTemplates.py or otherwise you check the doctests of zope.pagetemplate. -ajThanks, Andreas. I'm using Zope 2.8, here (yes, I know it is old software; yes, I know, I should switch; yes, I will do soon, I promise :-) ))
In Zope 2.8 you could use the ZopePageTemplate class. Something like pt = ZopePageTemplate() pt.pt_edit(zpt_source_code) xml = pt.pt_render(...)should work. The unit tests (or the code) should show you how to specify text/xml as mime-type and how to pass the options/parameters to the template.
