since you are the creator of XML documents, I wanted to ask you whether the node IDs in the XML document tree are not necessarily unique. I have a XML document and I try to create an index. I planned of using the node IDs from the tree as my identifiers. But I noticed that I have an ID twice. Yes, it is at a different level of the tree.
Is this a bug? Is there another way to accomplish my task?
This is not a bug. It is possible to have a URL like this e5/e5/e17 The normal way to get a unique identifier for Zope objects including Elements of an XML Document for the purposes of indexing is to use a full URL such as FolderA/FolderB/myXMLDoc/e12/e15/e15 One important thing to note about XML Document elements is that when you re-parse the XML, the parser will create new nodes that probably won't have the same ids as the old ones. This means you'll have to rebuild your indexes when you re-parse your xml. In the future I'll probably add something like <foo zope:id="e15">blah</foo> to help solve this problem. This is a little ways off though. I've got to get XML Document doing namespaces first, plus more thought (and discussion with Jim ;-) needs to go into this first. Hope this helps. -Amos
