nokogiri 1.5.6 breaks roo gem openoffice ods parsing

[dc7kr]

Updating my bundle to nokogiri 1.5.6 breaks roo ods spreadsheet parsing.

Steps to reproduce: install nokogiri 1.5.6 and roo 1.10.1 gems and exec the following ruby code:
require 'rubygems'
require 'roo'
doc = Openoffice.new("some.ods")
doc.sheets.each do |s|
puts s
end
No sheets are found as it cannot parse the sheets correctly.

downgrade nokogiri to 1.5.5. and re-run and it correctly displays all sheet names.

Not sure whether this is a bug in nokogiri or a change in the API that causes the roo gem to break.

Hi! Thanks for reporting this issue.

Have you brought this up with the maintainer of roo? I'm happy to help diagnose, but without more information I can't promise there's anything we can do about it.

Can you provide a sample ods file so that I am reproducing exactly what you're describing?

Hi,

thanks for your reply. I did not yet notify the roo maintainers about this issue - I'd be grateful for a pointer to their
current bugtracker - found some related pages on the web (also a github page) but nothing recent. (my gem version is 1.10.1).

Regarding reproducibility: any ODS will do - simply create an empty spreadsheet, add some sheets and give one of the sheets a well defined name for later recognition in the ruby code.

If you for example do

doc.default_sheet = "MyWellDefinedTitle" 

it works fine with 1.5.5 but gives a "RangeError" exception when using nokogiri 1.5.6.

Best regards

Karsten

Hi,

I just found out that this is related to the issue #816

roo uses the [] operator to retrieve attribute values which as it seems now needs the namespaces
table names are found using table['name'] which now has to be table['table:name']

As #816 seems to be an API change and not a bug I vote for closing this bug.

Closing, per your request.
