C# 在C中使用XSLT合并具有不同节点结构的多个XML文件#

我在使用C#中的XSL transromation合并多个文件时遇到问题。我跟随了几个来自sevreal网站的例子和帖子，我很接近，但没有乐趣。我在运行代码时遇到一个错误，该代码声明“在添加属性节点之后，无法将命名空间节点添加到父元素。”

这是到目前为止我的代码

string[] filesInCurrentDir = Directory.GetFiles(dirsWithTestCases[a], "*.xml");
string[] xslFilePath = Directory.GetFiles(dirsWithTestCases[a], "*.xsl");
string[] outputPathArray = Directory.GetFiles(dirsWithTestCases[a] + "\\Expected");
var resolver = new XmlPreloadedResolver();
var inputPath = string.Empty;    
for (int x = 0; x < filesInCurrentDir.Length; x++)
{
    if (filesInCurrentDir[x].IndexOf(".xml") > 0)
    {
        // First file load into doc variable
        if (inputPath == string.Empty)
        {
            // Load the first XML file into a document
            //input.LoadXml(filesInCurrentDir[x]);
            inputPath = filesInCurrentDir[x];
        }
        //Any and all other files
        else
        {
            var files = new FileInfo(filesInCurrentDir[x]);
            var inputStream = files.OpenRead();
            resolver.Add(new Uri(filesInCurrentDir[x]), inputStream);
        }
    }
}
// Load the XSL
var xslt = new XslCompiledTransform(true);
var xlstFile = new FileInfo(xslFilePath[0]);
var xsltDoc = new XmlDocument();
// Load the XSLT file through XmlReader to override the base URI.
using (StreamReader reader = File.OpenText(xslFilePath[0]))
using (XmlReader xmlReader = XmlReader.Create(reader, null, xslFilePath[0]))
{
    xsltDoc.Load(xmlReader);
}
// Use XsltSettings to enable the use of the document() function.
xslt.Load(xsltDoc, new XsltSettings(true, false), null);

// Define the output
var output = new FileInfo(outputPathArray[0] + ".UPDATED");

// Create input stream for first file
var inputFile = new FileInfo(inputPath);
//var inputStream = inputFile.OpenRead();
var input = new XmlDocument();
input.Load(inputPath);

// Compile stylesheet
var processor = new Processor();
var compiler = processor.NewXsltCompiler();
var executable = compiler.Compile(new Uri(xlstFile.FullName));

using (StringWriter OutputWriter = new StringWriter())
using (XmlWriter xmlWriter = XmlWriter.Create(OutputWriter))
{
    // Pass the resolver to the transform

    XmlWriterSettings settings = new XmlWriterSettings
    {
        Indent = true
    };
    var inputUri = new Uri(inputPath);
    xslt.Transform(input, xmlWriter);
}

错误：

“在已添加属性节点后，无法将命名空间节点添加到父元素。”

干杯

问题出在您的XSLT代码中，您还没有向我们展示。嗨，Michael，谢谢您的回复。我正试图调试XSLT，看看这是否是问题所在，但我真的不知道如何去做。我知道VS2017有这个功能，但是调试XSLT按钮变灰了。这些XSLT是由Contivo Analyst生成的，因此它们不是手工编写的。我不知道我是否可以透露，因为它们属于我的客户，但我想我可以直接发送给你让你查看？对不起，这不是它的工作方式。如果你想要付费的XSLT咨询服务，我相信会有一些优秀的人来接手，但不会是我。当然，我理解。我将看看我的客户机是否允许我在这里发布XSLT和XML消息。现在谢谢你。
