Re: [nokogiri-talk] Cannot access namespaced attribute?

[Mike Dalessio]

Hello!

Can you please reply with a code that reproduces the behavior you think Nokogiri should demonstrate?

Thanks so much!

Hi there,

If I have an element like this:

#<Nokogiri::XML::Element:0x1650b48 name="title" namespace=#<Nokogiri::XML::Namespace:0x169160c prefix="dc" href="http://purl.org/dc/elements/1.1/"> attributes=[#<Nokogiri::XML::Attr:0x1650ad0 name="lang" namespace=#<Nokogiri::XML::Namespace:0x16502b0 prefix="xml" href="http://www.w3.org/XML/1998/namespace"> value="EN">] children=[#<Nokogiri::XML::Text:0x163fc6c "Austria">]>

Shouldn't e['lang'] return the lang attribute?

Thanks a lot,

Christoph

Thanks for your reply Mike.

This is the XML:

<geo:Countries xmlns:geo="http://schema.seekda.com/geo"

  xmlns:dc="http://purl.org/dc/elements/1.1/" 

  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:schemaLocation="http://schema.seekda.com/geo geo.xsd">

  <geo:Country isoCode="AT">

    <dc:title xml:lang="EN">Austria</dc:title>

  </geo:Country>                                                                                                                              

</geo:Countries>

For the above, unfortunately I don't have more code currently as this is nokogori used inside the happymapper library.

I just inspected the element and saw that the attribute 'lang' is actually there as a Nokogiri object, but that it is not returned with ['lang'] - I have no idea why...

Is there something that prevents this? Or did I misunderstand how to access attributes?

Thanks,

Christoph

node['xml:lang'] should do you fine. This is similar behaviour to more or less every other major XML parser that exists, and how the JRuby implementation of Nokogiri has worked for a long time. The libxml implementation was fixed in 1.5.something at my request to match. It should be in the changelog somewhere.

Namespaced attributes are _really_ confusing (as if namespaced elements
weren't confusing enough).

I'm not entirely sure what the 'correct' behavior is, and would urge
caution in making a potentially backwards-incompat change based on one
use case.

First to figure out what's going on now exactly, what happens if you
have ask for e.attributes, what do you get?

Ah! I didn't try that :/

Thanks a lot!

I can tell you how to do this using the Nokogiri API, but it sounds like that won't help you, since you're using another gem.

How can I help you?
