Hi there I use Zope 2.10.5 and I want to create a site tree using the ZCatalog instead of iterating recursive trough the entire object tree. I have the following site structure (all things are folders): - about --- company --- staff ----- homepages ------- phelps --- phonebook --- jobs - research --- ocean ----- atlantic ----- pacific --- lake --- river My ZCatalog contains these entries: - /research - /research/ocean - /research/ocean/pacific - /research/ocean/atlantic - /research/lake - /research/river - /about - /about/company - /about/staff - /about/staff/homepages - /about/staff/homepages/phelps - /about/staff/phonebook - /about/jobs - /about What I need is a list of these entries ordered according to the site structure. I would like to get this list: ['/about', '/about/company', '/about/staff', '/about/staff/homepages', '/about/staff/homepages/phelps', '/about/phonebook', '/about/jobs', '/research', '/research/ocean', '/research/ocean/atlantic', '/research/ocean/pacific', '/research/lake', '/research/river' ] My Zcatalog is configured as follows: Indexes: - path - position - title - id Metadata: - physical_path - title - id The index 'position' contains the a folder's position in it's parent folder. In my example the folder "phonebook" contains "3" for position because it is in the 3rd position inside it's parent folder ("about"). Is it possible to build an ordered site tree with the ZCatalog only and if so, any ideas how I can do that? Regards Nico
