Eu estou usando o Nokogiri para analisar um arquivo XML e não está funcionando.
Quando eu estou a tentar agarrar a partir de um nó de três níveis, ela está agarrando os dados a partir do primeiro nó do tipo.Eu tenho depurado e o nó é sobre deveria ser o direito um para obter os dados de que preciso, mas é ainda puxando o formulário de dados o primeiro nó do tipo.
Os itens que não estão no nível superior, os nós são a saída para o arquivo de bom, mas quando eu começar a mover-se até a árvore é escrever errado dados para o arquivo.
require 'nokogiri'
f = File.new("grammystext.txt", "w+")
x = File.open("items.xml", "r")
doc = Nokogiri::XML(x)
x.close
doc.xpath('//CWItemExport//ItemExportData//CWItem//ProductID//ItemColor//ItemSize').each_with_index do |item, i|

Esta é a minha primeira vez usando o Nokogiri para que eu possa estar fazendo algo errado aqui.
Solução
Problema
O problema é o início do xpaths com //.Este diz para localizar o nó em qualquer lugar no documento.
No exemplo a seguir simplificado, você pode ver que usando // resultados no mesmo subitem ser devolvidos (ao invés de incluir o subitem do item da iteração).
require 'nokogiri'
xml = %Q{
<root>
<item>
<subitem>1</subitem>
</item>
<item>
<subitem>2</subitem>
</item>
</root>
}
doc = Nokogiri::XML(xml)
doc.xpath('//root//item').each_with_index do |item, i|
puts item.at_xpath('//subitem').content
end
#=> 1
#=> 1
Se você quiser procurar em qualquer lugar dentro de um nó específico, você precisa começar com um período - ie .//.Aplicando-se este para o exemplo simplificado, você pode ver que nós temos esperado subitem resultados:
doc = Nokogiri::XML(xml)
doc.xpath('//root//item').each_with_index do |item, i|
puts item.at_xpath('.//subitem').content
end
#=> 1
#=> 2
Solução
Para o seu problema específico, você deve alterar o xpaths na iteração dos itens a incluir o . no início.Por exemplo, a linha:
f << item.parent.parent.parent.at_xpath('//CWVendor//VendorCode').content + ", "
Deve ser alterado para:
f << item.parent.parent.parent.at_xpath('.//CWVendor//VendorCode').content + ", "
Em geral, este dar-lhe-ia:
doc.xpath('.//CWItemExport//ItemExportData//CWItem//ProductID//ItemColor//ItemSize').each_with_index do |item, i|
f << item.parent.parent.parent.at_xpath('.//CWVendor//VendorCode').content + ", "
f << item.parent.parent.parent.at_xpath('.//CWVendor//VendorName').content + ", "
f << item.parent.parent.parent.at_xpath('.//ItemStyle').content + ", "
f << item.parent.parent.parent.at_xpath('.//ItemDescription').content + ", "
f << item.parent.parent.parent.at_xpath('.//TaxID//TaxIDCode').content + ", "
f << item.parent.parent.parent.at_xpath('.//ItemDepartment//ItemDeptCode').content + ", "
f << item.parent.parent.parent.at_xpath('.//ItemDepartment//ItemDeptName').content + ", "
f << item.parent.parent.parent.at_xpath('.//ItemClass//ItemClassCode').content + ", "
f << item.parent.parent.parent.at_xpath('.//ItemClass//ItemClassName').content + ", "
f << item.attr("MainSize") + ", "
f << item.at_xpath('Sku').content + ", "
f << item.at_xpath('.//ReplacementCost').content + ", "
f << item.at_xpath('.//CurrentRetail').content + "\n"
puts item.parent.parent.parent if i == 6
break if i == 7
end

Nota:Eu também recomendaria o uso de um único / em vez de // a menos que a estrutura não é conhecido.O / verifica direta nós filhos, o que torna mais fácil a depuração se você obter resultados inesperados.
Outras dicas
Isso vai ser um pouco de um revisão de código, mas espero que isso irá ajudá-lo com seu futuro de análise.
Se você estiver indo para criar CSV, eu altamente recomendamos que você use o CSV gem.Isso garante que você não criar quebrado CSV (que o código seria criar um momento de campos contém uma vírgula).Além disso, ele permite que você para ser um pouco mais descritivo, usando nomes de variáveis.
Como foi mencionado por outras pessoas, não use
//se você pode usar/.Há uma penalidade de desempenho, além de não ser o que você realmente deseja em alguns casos.A proliferação de
item.parent.parent.parentme diz que você foi longe demais a árvore em seu caminho.Tire vantagem de XPath é predicados (em[]) para garantir que você está no nível correto.Além disso, como estamos aproveitando o XPath, você não vai precisar de um índice ou de uma
breakquando você diz XPath, para não dar-lhe mais do que os 7 primeiros.Eu não implementar esse dado seus dados eu não tenho certeza se você precisa de nada disso.
Exemplo:
CSV.open("grammystext.csv", "wb") do |csv|
items = doc.xpath('/CWItemExport/ItemExportData/CWItem[ProductID/ItemColor/ItemSize]') items.each do |item|
vendor_code = item.at_xpath('CWVendor/VendorCode').text
vendor_name = item.at_xpath('CWVendor/VendorName').text
item_style = item.at_xpath('ItemStyle').text
...
main_size = item.at_xpath('ProductID/ItemColor/ItemSize')['MainSize']
sku = item.at_xpath('ProductID/ItemColor/ItemSize/Sku').text
csv << [vendor_code, vendor_name, item_style, ... , main_size, sku]
end
end
