Flooding of warning saying: "element span: validity error : ID login_btn already defined"

[Basher52]

Hi

I'm using nokogumbo as a parser and I'm getting flooded with warnings/messages saying:
element span: validity error : ID login_btn already defined

I boiled down my code and was able to reproduce it with the following code:
require 'open-uri'
require 'nokogumbo'
file = open('http://www.motogp.com/en/Results+Statistics')
doc = Nokogiri::HTML5(file)

The error comes out 2x after performing the 'doc = Nokogiri::HTML5(file)' command.

Would it be possible to supress this message/warning?
Thanks for the help!
Cheers

This message is not put out by nokogiri. It seems to be a problem in libxml2.

Issue sparklemotion/nokogiri#1208 was closed with a message that sparklemotion/nokogiri#1196 was re-opened. Issue sparklemotion/nokogiri#1196 was closed saying open a new issue.

On further investigation, it appears that libxml2 changed, and nokogiri had to change to capture these messages, and that a similar fix is necessary to nokogumbo.

I'm still new to github, but i think i understand that your commit should now supress these messages.
So by updating my nokogumbo I assume it should be fixed.
Thanks a lot for the effort and help!

hold back for the moment, this fix is broken, I'm still chasing down what the real fix should be.

Roger that, I'm not home at the moment but thanks for the heads up

@rubys Let me know if I can assist in any way, having been through a few iterations of this fix on Nokogiri already. ;)

Reproducible test case for the problem, with no Nokogumbo:

require 'nokogiri'
doc = Nokogiri::HTML::Document.new()
x1 = Nokogiri::XML::Element.new('a', doc)
x1.set_attribute('id', 'x')
x2 = Nokogiri::XML::Element.new('a', doc)
x2.set_attribute('id', 'x')

Opened as sparklemotion/nokogiri#1262

Isn’t this back? I’m having such warnings when using Nokogumbo only, not with plain Nokogiri.

require 'nokogumbo'
Nokogiri::HTML5('<p id="foo"></p><p id="foo"></p>')
# => element p: validity error : ID foo already defined

require 'nokogiri'
Nokogiri::HTML('<p id="foo"></p><p id="foo"></p>')
# => nothing

Nokogiri: 1.6.7.2
Nokogumbo: 1.4.7

UPDATE: This is gone from later versions.
