Yes, of course you are right again.

This time I hand-tested against the output that you listed in your
previous email, and it seems to work. Third time's the charm?

Suggestion incorporated.

I just intentionally broke the code for "svn proplist -v" (without
--xml) and several test cases in prop_test.py broke. So there is at
least some level of testing aside from tree.get_props().

The xml.dom.minidom parser (which I'm using) was added in Python 2.0.

Read svn properties in XML rather than text format in test suite.

This makes the routine more robust to strange property values. It also
makes it immune to changes in the text output format, as happened
between svn 1.5 and 1.6. (This is useful for the cvs2svn project,
which uses the svntest infrastructure but doesn't want to care what
version of svn the user has installed.)

* subversion/tests/cmdline/svntest/tree.py
  (get_props): Read svn properties via "svn proplist -v" using the
  "--xml" option.
