Nokogiri在XML中获取错误的节点数据

Question

我正在使用Nokogiri解析XML文件，但它不起作用。

当我试图从三级以上的节点获取数据时，它就是从该类型的第一个节点获取数据。我已经调试过它，它所在的节点应该是获得我需要的数据的正确节点，但它仍然从该类型的第一个节点提取数据。

不在更高级别节点中的项目会很好地输出到文件中，但当我开始向上移动树时，它会向文件中写入错误的数据。

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|
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
f.close

这是我第一次使用Nokogiri，所以我可能在这里做错了什么。

Answer 1

问题

问题是使用//启动xpath。这表示将节点定位在文档中的任何位置。

在下面的简化示例中，您可以看到使用//会导致返回相同的子项(而不是迭代项的子项)。

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

如果要查看特定节点中的任何位置，则需要从句点(即.//)开始。将此应用于简化示例，您可以看到我们得到了预期的子项结果：

doc = Nokogiri::XML(xml)
doc.xpath('//root//item').each_with_index do |item, i|
puts item.at_xpath('.//subitem').content
end
#=> 1
#=> 2

解决方案

对于您的特定问题，您应该在项的迭代中更改xpath，以便在开始时包含.。例如：

f << item.parent.parent.parent.at_xpath('//CWVendor//VendorCode').content + ", "

将更改为：

f << item.parent.parent.parent.at_xpath('.//CWVendor//VendorCode').content + ", "

总的来说，这会给你：

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

结果：

5TH, 5TH SUN, AMM024-B105, CALVERY, 0, APPAR, APPAR, TEE, TEE-SHIRTS, L, 400100018477, 44.80, 199.00
5TH, 5TH SUN, AMM024-B105, CALVERY, 0, APPAR, APPAR, TEE, TEE-SHIRTS, M, 400100018460, 44.80, 199.00
5TH, 5TH SUN, AMM024-B105, CALVERY, 0, APPAR, APPAR, TEE, TEE-SHIRTS, S, 400100018453, 44.80, 199.00
5TH, 5TH SUN, AMM024-B105, CALVERY, 0, APPAR, APPAR, TEE, TEE-SHIRTS, XL, 400100018484, 44.80, 199.00
5TH, 5TH SUN, AMM024-B105, CALVERY, 0, APPAR, APPAR, TEE, TEE-SHIRTS, XS, 400100031704, 44.80, 199.00
5TH, 5TH SUN, AMM024-B105, CALVERY, 0, APPAR, APPAR, TEE, TEE-SHIRTS, XXL, 400100035801, 44.80, 199.00
5TH, 5TH SUN, AMM025-B105, WINGMAN, 0, APPAR, APPAR, TEE, TEE-SHIRTS, L, 400100018514, 44.80, 199.00

注意：我还建议使用单个/而不是//，除非结构未知。/检查直接子节点，这样在得到意外结果时更容易调试。

Answer 2

这将是一个代码审查，但希望它能帮助您进行未来的解析。

1. 如果您要创建CSV，我强烈建议您使用CSV gem。它保证你不会创建损坏的CSV(当其中一个字段包含逗号时，你的代码就会创建它)。此外，它还允许您使用变量名进行更多的描述。

2. 正如其他人所提到的，如果可以使用/，就不要使用//。在某些情况下，除了不是你真正想要的之外，还有表现方面的惩罚。

3. item.parent.parent.parent的激增告诉我你走得太远了。利用XPath的谓词(在[]中)来确保您处于正确的级别。

4. 此外，只要我们利用XPath，当您告诉XPath不要给您超过前7个时，就不需要索引或break。我没有实现这个，因为考虑到你的数据，我不确定你是否需要它。

示例：

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

您可以在grammystext.txt文件中获得以下内容：

5TH, 5TH SUN, AMM024-B105, CALVERY, 0, APPAR, APPAR, TEE, TEE-SHIRTS, L, 400100018477, 44.80, 199.00
5TH, 5TH SUN, AMM024-B105, CALVERY, 0, APPAR, APPAR, TEE, TEE-SHIRTS, M, 400100018460, 44.80, 199.00
5TH, 5TH SUN, AMM024-B105, CALVERY, 0, APPAR, APPAR, TEE, TEE-SHIRTS, S, 400100018453, 44.80, 199.00

或者，您可以在读取文件后添加所需的元素：

require 'nokogiri'
f = File.new("grammystext.txt", "w+")
x = File.open("items.xml", "r")
xml = "<CWItemExport><ItemExportData>#{x.read}</CWItemExport></ItemExportData>"
doc = Nokogiri::XML(xml)
x.close
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('//ItemDepartment//ItemDeptCode').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
f.close
