Building tree structure from flat list derived from zope catalog call without recursion

Question

I have all objects which get looked up to provide interpreter with both parents objects and object subobjects. I hope to do this without recursion for zope not appreciating this conventional recursion.

I set the view context as root object for recursion to start attaching object on then iterate across this filtered list of intid/objects looking for object that has this object as parent. From there I seek starter code with hopes someone help me.

Maybe this little trick will be usefull for you as it was for me.
You can restrict your search results by PathIndex (getPhysicalPath) and then just sort it alphabetically:

lst = context.Catalog.searchResults(path='/parentNodeId')
lst.sort()
print lst

You will see something like this:

# /parentNodeId/
# /parentNodeId/folder/
# /parentNodeId/folder/file1.jpg
# /parentNodeId/folder/file2.jpg
# /parentNodeId/folder/file1.jpg
# /parentNodeId/folder2/
# /parentNodeId/folder3/
# /parentNodeId/folder3/file1.jpg
# /parentNodeId/folder3/file2.jpg

I think from this output you can easy build a tree structure
