All elements with namespace a parsed as expected with follow definition:

require "happymapper"


class AppMapper
  include ::HappyMapper

  namespace "a"
  tag       "feed"

  element :updated,             DateTime
  element :title,               String
  element :id,                  String
  element :description,         String,   tag: "content"
  element :publisher_url,       String,   tag: "publisherUrl", namespace: nil
end

But publisher_url field wasn't parsed.

I tried different combinations of xpath, tag, namespace options, but neither is working.
When I load this document to Nokogiri. I was able to access element with follow xpath expression: /a:feed/xmlns:publisherUrl

xml = File.read("/tmp/27f2e0ef-5a0c-4dca-a383-b89f9485b9d2.xml")
doc = ::Nokogiri::XML(xml)
doc.xpath("/a:feed/xmlns:publisherUrl").text # => "http://www.vectorunit.com/beach-buggy-racing"

Versions:
ruby: 2.2.1
nokogiri: 1.6.6.2
nokogiri-happymapper: 0.5.9

Does anyone know whether it possible to map such xml using nokogiri-happymapper?

@zekefast Better ask on StackOverflow

If I remember correctly, it's hard for the elements defined in the class to shake the namespace that was given to them. It's most likely a bug. So you can get around that by creating another class for the element.

require "happymapper"

class PublisherUrl
  include ::HappyMapper

  content :url, String
end

class AppMapper
  include ::HappyMapper

  namespace "a"
  tag       "feed"

  element :updated,             DateTime
  element :title,               String
  element :id,                  String
  element :description,         String,   tag: "content"
  # element :publisher_url,       String,   tag: "publisherUrl", namespace: nil

  def publisher_url
    publisher_url_object.url
  end
  element :publisher_url_object,       PublisherUrl,   tag: "publisherUrl"
end


app = AppMapper.parse(File.read('buggy.xml'))
puts "Publisher #{app.publisher_url}"

Oh yeah, here is the issue: #43
