如何使用 Nokogiri 解析带有非配对标签的 XML

Question

在 Internet 上看到的所有示例都是 XML 结构如下的文件：

<open_tag>data that I want</close_tag>

但我的 XML 文件不同：

<Report xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="_x0034_00_x0020_-_x0020_Nomenklatury" xsi:schemaLocation="_x0034_00_x0020_-_x0020_Nomenklatury http://pcisrs/ReportServer?%2FTARIC%20Reporty%20Ciselnikov%2F400%20-%20Nomenklatury&rs%3AFormat=XML&rc%3ASchema=True" Name="400 - Nomenklatury">
<table1>
<Detail_Collection>
<Detail goods_nomenclature_item_id="0100000000" product_line="80" date_start="31.12.1971" quantity_indents="0" declarable_import="0" declarable_export="0" goods_nomenclature_item_description="ŽIVÉ ZVIERATÁ"/>
<Detail goods_nomenclature_item_id="0101000000" product_line="80" date_start="01.01.1972" quantity_indents="1" statistical_unit="NAR" declarable_import="0" declarable_export="0" goods_nomenclature_item_description="Živé kone, somáre, muly a mulice" parent_goods_nomenclature_item_id="0100000000" parent_product_line="80"/>

.....ETC....

</Detail_Collection>
</table1>
</Report>

如果我理解教程，这应该可行：

 subor = Nokogiri::XML(File.open('vendor/financnasprava/nomenklatury/recent.xml'))
    dataset = subor.xpath('//Detail')

但没有。

您可以像下面的示例一样使用这些数据。我删除了源路径，因为我在本地没有此数据。

如果我是对的并且您正在尝试访问详细信息属性：

require 'nokogiri'
require 'open-uri'

data_xml = <<-EOT
<Report xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" Name="400 - Nomenklatury">
<table1>
<Detail_Collection>
<Detail goods_nomenclature_item_id="0100000000" product_line="80" date_start="31.12.1971" quantity_indents="0" declarable_import="0" declarable_export="0" goods_nomenclature_item_description="ŽIVÉ ZVIERATÁ"/>
<Detail goods_nomenclature_item_id="0101000000" product_line="80" date_start="01.01.1972" quantity_indents="1" statistical_unit="NAR" declarable_import="0" declarable_export="0" goods_nomenclature_item_description="Živé kone, somáre, muly a mulice" parent_goods_nomenclature_item_id="0100000000" parent_product_line="80"/>
</Detail_Collection>
</table1>
</Report>
EOT
subor = Nokogiri::XML(data_xml)
dataset = subor.xpath('//Detail_Collection/*')
details = dataset.map do |row|
  {
    product_line: row.attributes['product_line'].value,
    goods_nomenclature_item_id: row.attributes['goods_nomenclature_item_id'].value
  }
end

puts details

#=> {:product_line=>"80", :goods_nomenclature_item_id=>"0100000000"}
#=> {:product_line=>"80", :goods_nomenclature_item_id=>"0101000000"}
