Allow attributes without namespace on jRuby

[ShockwaveNN]

Hi, trying to port one of my library for parsing ooxml to jruby and I got a problem

I got this XML

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<workbook xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main"
          xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
  <bookViews>
    <workbookView r:xWindow="360" yWindow="15" windowWidth="20955"
                  windowHeight="9720" activeTab="0"/>
  </bookViews>
</workbook>

And simplified ruby code to parse it:

require 'nokogiri'
xml = Nokogiri::XML(File.open('example.xml'), &:strict)
xml.xpath('xmlns:workbook/xmlns:bookViews/xmlns:workbookView').each do |sheet|
  puts sheet.attribute('xWindow').value
end

On mruby this output 360

But on jruby it just crash with:

NoMethodError: undefined method `value' for nil:NilClass

If I change puts to

  puts sheet.attribute('r:xWindow').value

It works correctly on both rubies

I understand that mruby and jruby uses different XML parser

Is there any option to jruby to make parsing of such attributes same as on jruby or proper way will be to fix my codebase by adding r: namespace?

Hi! This looks like a bug in the JRuby implementation. I've created a bug report at #2677
