Subversion: Generating a sortable list of changes made to a branch

I needed to generate a sortable list of all the changes made to a branch in subversion. svn log dumps a list, but is very difficult to sort, based on users, time, etc. I wrote a script based on a ruby script to dump the data in a comma separated format, that can then me loaded in Excel to analyze. Here is the script

# This script allows the svn log to be dumped as a comma separated list so that the data can be analyzed in excel
#!/usr/bin/ruby
require 'rubygems'
require 'hpricot'

username = ARGV[1]
svnUrl = ARGV[0]

#puts "Requesting SVN log, this may take a bit."

doc = IO.popen("svn log --xml -v --stop-on-copy " + svnUrl) do |f|
 Hpricot.XML(f)
end

entries = doc.search("logentry").find_all do |entry|
 if(username != nil)
   (entry/"author").innerHTML == username
 else
   true
 end
end

puts "Revision,Author,Date,Action,Path,Message"
entries.each do |entry|
 revision = entry.attributes["revision"]
 author = (entry/"author").innerHTML
 date = (entry/"date").innerHTML
 msg = (entry/"msg").innerHTML
 paths = (entry/"paths").search("/path")
 paths.each do |path|
   action = path.attributes["action"]
   puts "#{revision},#{author},#{date}, #{action}, #{ path.innerHTML}, #{msg.gsub("\n", " ")}"
 end

end
