Re: XML Base relative URI resolution tests

Here's how DanC's code does them:

>>> import uripath
>>> print uripath.join.__doc__
join an absolute URI and URI reference

    here must be an absolute URI.
    there must be a URI reference

    Raise ValueError if there uses relative path
    syntax but here has no hierarchical path.
    
>>> #EASY:
... uripath.join("http://example.org/dir/file", "../relfile")
'http://example.org/relfile'
>>> uripath.join("http://example.org/dir/file", "/absfile")
'http://example.org/absfile'
>>> uripath.join("http://example.org/dir/file", "//another.example.org/absfile")
'http://another.example.org/absfile'
>>> 
>>> #GETTING HARDER:
... uripath.join("http://example.org/dir/file", "../../../relfile")
'http://example.org/relfile'
>>> uripath.join("http://example.org/dir/file", "")
'http://example.org/dir/file'
>>> uripath.join("http://example.org/dir/file", "#frag")
'http://example.org/dir/file#frag'
>>> 
>>> #MASTER CLASS:
... uripath.join("http://example.org", "relfile")
'http://example.org/relfile'
>>> 
>>> uripath.join("http://example.org/dir/file#frag", "relfile")

Here's the code I used:
import uripath
#EASY:
uripath.join("http://example.org/dir/file", "../relfile")
uripath.join("http://example.org/dir/file", "/absfile")
uripath.join("http://example.org/dir/file", "//another.example.org/absfile")

#GETTING HARDER:
uripath.join("http://example.org/dir/file", "../../../relfile")
uripath.join("http://example.org/dir/file", "")
uripath.join("http://example.org/dir/file", "#frag")

#MASTER CLASS:
uripath.join("http://example.org", "relfile")

uripath.join("http://example.org/dir/file#frag", "relfile")
uripath.join("http://example.org/dir/file#frag", "#foo")
uripath.join("http://example.org/dir/file#frag", "")

uripath.join("mailto:Jeremy_Carroll@hp.com", "#foo")
uripath.join("mailto:Jeremy_Carroll@hp.com", "")
uripath.join("mailto:Jeremy_Carroll@hp.com", "relfile")

All the best,
