Hello, I'm writing a product which stores the equivalent of Folder properties in XML. Now I want to be able to catalog objects of this type, but looking at how that's done by the ZCatalog shows that getattr(object, index) is called for all indexes. How do I overload getattr to parse my XML and return the value of the "property". My product is subclassed from ParsedXML and uses the DOM to go through the tree and find my "properties". What seems to be happening is that when I define a new __getattr__, implicit getattr calls are made to the DOM object and it ends up calling my newly defined getattr method. This sort of send it into a recursive neverending loop. -Chris
