RubyZipFIleSystem - help with simple task

[Nathan Loyer]

I am new to Ruby, but am doing my best. I have a zip file that I'm
trying to open, go to directory "word" and read one of the files out.
Here is what I have so far:

require 'rubygems'
require 'zip/zipfilesystem'

Zip::ZipFile.open("Evelyn Attwood.docx.zip") {
|zipfile|
zipfile.dir.open("word")
puts zipfile.file.read("document.xml")
}

Simple, but I get an error:

ruby docxreader.rb
/Library/Ruby/Gems/1.8/gems/rubyzip-0.9.1/lib/zip/zipfilesystem.rb:371:in
`stat': No such file or directory - word (Errno::ENOENT)
from
/Library/Ruby/Gems/1.8/gems/rubyzip-0.9.1/lib/zip/zipfilesystem.rb:463:in
`foreach'
from
/Library/Ruby/Gems/1.8/gems/rubyzip-0.9.1/lib/zip/zipfilesystem.rb:458:in
`entries'
from
/Library/Ruby/Gems/1.8/gems/rubyzip-0.9.1/lib/zip/zipfilesystem.rb:430:in
`new'
from
/Library/Ruby/Gems/1.8/gems/rubyzip-0.9.1/lib/zip/zipfilesystem.rb:434:in
`open'
from docxreader.rb:6
from /Library/Ruby/Gems/1.8/gems/rubyzip-0.9.1/lib/zip/zip.rb:1382:in
`open'
from docxreader.rb:4


But there is certainly such a file. What am I doing wrong?

Much thanks,

Nathan

Probably this archive does not contain the folder.
Please try out:

require 'rubygems'
require 'zip/zipfilesystem'

Zip::ZipFile.open("Evelyn Attwood.docx.zip") do |zipfile|
puts zipfile.file.read('word/document.xml')
end

That works! Thank you. Can you explain why though? When I unzip the
archive, I see the folder. Is there a difference between a "directory"
and a folder in a zip file?

There is no folder/directory difference - it is the same thing. But you
may have it included in file or not.

Example:

$ zip document.zip document/sample.xml
adding: document/sample.xml (stored 0%)

$ unzip -l document.zip
Archive: document.zip
Length Date Time Name
-------- ---- ---- ----
0 08-07-08 13:39 document/
0 08-07-08 13:39 document/sample.xml
-------- -------
0 2 files

But if you create it using file-roller you don't have directory
included:

$ unzip -l document.zip
Archive: document.zip
Length Date Time Name
-------- ---- ---- ----
0 08-07-08 13:39 document/sample.xml
-------- -------
0 1 file

Thats all.
