Question

我有一个 json，我想为电子发票创建特定的 XML 格式。

你能帮我找到实现这一目标的最佳解决方案吗？我正在使用 .net core 3.1

我现在的问题是命名空间和前缀

<InvoicesDoc xmlns="http://www.aade.gr/myDATA/invoice/v1.0"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.aade.gr/myDATA/invoice/v1.0/InvoicesDoc-v0.6.xsd"   
        xmlns:icls="https://www.aade.gr/myDATA/incomeClassificaton/v1.0"
        xmlns:ecls="https://www.aade.gr/myDATA/expensesClassificaton/v1.0">

...

<incomeClassification>
                <icls:classificationType>E3_561_001</icls:classificationType>
                <icls:classificationCategory>category1_2</icls:classificationCategory>
                <icls:amount>1000.00</icls:amount>               
</incomeClassification>

Answer 1

命名空间很棘手。所以我喜欢解析字符串，这比在代码中尝试更容易。这是使用 xml linq 的示例：

using System;
using System.Collections.Generic;
using System.Collections;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
         static void Main(string[] args)
        {
             string ident = 
                 "<InvoicesDoc xmlns=\"http://www.aade.gr/myDATA/invoice/v1.0\"" +  
                 " xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"" +
                 " xmlns:icls=\"https://www.aade.gr/myDATA/incomeClassificaton/v1.0\"" +
                 " xmlns:ecls=\"https://www.aade.gr/myDATA/expensesClassificaton/v1.0\"" +
                 " xsi:schemaLocation=\"http://www.aade.gr/myDATA/invoice/v1.0/InvoicesDoc-v0.6.xsd\">" +
                 "</InvoicesDoc>";

             XDocument doc = XDocument.Parse(ident);
             XElement invoicesDoc = doc.Root;
             XNamespace ns = invoicesDoc.GetDefaultNamespace();
             XNamespace nsIcls = invoicesDoc.GetNamespaceOfPrefix("icls");
             XNamespace nsEcls = invoicesDoc.GetNamespaceOfPrefix("ecls");
             XElement invoice = new XElement(ns + "invoice");
             invoicesDoc.Add(invoice);

             XElement incomeClassification = new XElement(ns + "incomeClassification", new object[] {
                 new XElement(nsIcls + "classificationType", "E3_561_001"),
                 new XElement(nsIcls + "classificationCategory", "category1_2"),
                 new XElement(nsIcls + "amount", 1000.00),
             });
             invoice.Add(incomeClassification);

        }
    }
  
}

您可以使用 XSLT 3.0，如下所示：

    <xsl:template name="xsl:initial-template">
      <xsl:variable name="in" select="json-doc('input-json.json')"/>
      <InvoicesDoc xmlns="http://www.aade.gr/myDATA/invoice/v1.0"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://www.aade.gr/myDATA/invoice/v1.0/InvoicesDoc-v0.6.xsd"   
            xmlns:icls="https://www.aade.gr/myDATA/incomeClassificaton/v1.0"
            xmlns:ecls="https://www.aade.gr/myDATA/expensesClassificaton/v1.0">
         <xsl:for-each select="$in?invoices?invoiceDetails?*">
           <incomeClassification>
             <icls:classificationType>{?incomeClassification?classificationType}</icls:classificationType>                           
             <icls:classificationCategory>{?incomeClassification?classificationCategory}</icls:classificationCategory>
             <icls:amount>{?incomeClassification?amount}</icls:amount>               
           </incomeClassification>
         </xsl:for-each>
      </InvoicesDoc>
    </xsl:template>

带有命名空间和前缀的 Json 到 XML
