您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>
【问题讨论】：
【参考方案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。这是一个使用 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);

谢谢。我会试试的！【参考方案2】：您可以按照以下思路使用 XSLT 3.0：
<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>
【讨论】：
请您提供有关带有 net core 3.1 的 xslt 3 的更多信息吗？我没有再用过。 目前有两种 XSLT 3.0 处理器可用：Altova 和 Saxon。 Saxon（我的产品）尚未在 .net 核心上运行（我们正在努力）。我不能代表阿尔托娃。提供有关某项技术的介绍性信息超出了 SO 答案的范围：如果您寻找它，周围有很多信息，而且您总是可以就特定点提出问题。以上是关于带有命名空间和前缀的 Json 到 XML的主要内容，如果未能解决你的问题，请参考以下文章
