generally dom objects need to be released to destroy them, doing a del doc, won't do it because of circular ref nature of dom. i'm guessing that you would need to call something akin to releaseNode from pyxml (xml.dom.ext) on the document to release it fully else you're likely to see the behavior you're seeing, namely dom objects staying in memory.

We aren't using circular refs in our DOM, so we don't have any way to release a DOM object - losing or deleting the reference should do it. If this isn't happening when the reference is going away, then this is either a Zope bug or a ParsedXML bug. I'd like to make sure that the ref really is going away, though :)

a quick browse through the source of ParsedXML doesn't offer any clues on how to release the object (or if its nescessary). its hard to say since acquisition is being used to help with the dom tree.

Acquisition is what we're currently using to avoid circular references. -- Karl Anderson karl@digicool.com
