RubyZipFIleSystem - help with simple task

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:inforeach’
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:innew’
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:inopen’
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

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. :slight_smile:

Maciej
