You've answered your own question. There is no end in the middle of
the path. The publisher picks off each part of the URL from the top
down, and at each step, it asks that object if it can provide the next
one. Look at traverse() in lib/python/ZPublisher/BaseRequest.py, or
step through the publishing process - see
At each step, the publisher checks to see if the parent has the child
as an attribute, and if so, continues with the object at that
attribute as the parent (so long as other conditions are met, like
You can see this in python products:
"a python product"
index_html = HTMLFile("someDTMLFile", globals())
index2_html = "<HEAD><BODY>..."
index3_html = aFunction(mood, phaseOfMoon)
Since getattr(path.to.foo, "index_html") reaches that html file,
ZPublisher.Zope("/path/to/foo/index_html") publishes that file.
index_html could be a (badly named) method instead, which has other
attributes. It could decide what to publish or how to allow
the publisher to traverse the path programmatically.
You don't need extra rules that look for foo.pl in the URL (what a
kluge - enforce a perl script to sit there until URLs are no more!).
For your example, script.pl could have two subobjects or other
attributes, 1234 and 2345, and the default index_html. Or script.pl
could be a ZClass with those three as DTML methods or other
__bobo_traverse__ is another attribute that the object may have to
drive the publishing process, but I haven't needed to understand why
it's useful yet :)
