如何将XML文件比较C＃？ [英] How to compare XML files in C#?

问题描述

我知道出现了很多这样的问题，但是我无法找到一个能够满足我的需求的答复。我必须写一个应用程序，将比较XML文件：将有2种类型的比较，首先为2档，列出所有的差异，第二个多个XML文件从均线列出所有的变化。

I know that there has been a lot of questions like this but I couldn't find a reply that would satisfy my needs. I have to write an application that will compare XML files: there will be 2 types of compare, first for 2 files, listing all the differences and second one for multiple XML files listing all the variations from averages.

我要寻找某种类，库或API的，这将帮助我完成这个任务。您能否提供一些解决方案？

I am looking for some kind of class, library or API that will help me finish this task. Can you suggest some solutions ?

可是，我不知道我是否应该使用DOM或XPath。有什么建议么 ？

And yet, I do not know if I should use DOM or Xpath. Any suggestions ?

编辑：

好了，所以我一直在试图完成该任务的xmldiff工具，但是这是很成问题要解决这个为多个XML文件 - 我不知道我怎么可以使用这个XmlDiffDiagram理清例如50 XML文件之间的差异

Ok so I have been trying to accomplish this task with XmlDiff tool but this is quite problematic to solve this for multiple Xml files - I have no idea how can I use this XmlDiffDiagram to sort out the differences among for instance 50 Xml files.

时它会与LINQ是更好？

Is it going to be better with LINQ ?

推荐答案

微软的 XML diff和patch API 应该很好地工作：

Microsoft's XML Diff and Patch API should work nicely:

public void GenerateDiffGram(string originalFile, string finalFile, XmlWriter diffGramWriter)
{
   XmlDiff xmldiff = new XmlDiff(XmlDiffOptions.IgnoreChildOrder |
       XmlDiffOptions.IgnoreNamespaces | XmlDiffOptions.IgnorePrefixes);

   bool bIdentical = xmldiff.Compare(originalFile, finalFile, false, diffGramWriter);
   diffgramWriter.Close();
}

如果你需要，你还可以使用修补工具比较的文件并将其合并：

If you need to, you can also use the Patch tool to compare the files and merge them:

public void PatchUp(string originalFile, string diffGramFile, string outputFile)
{
    var doc = new XmlDocument();
    doc.Load(originalFile);

    using (var reader = XmlReader.Create(diffGramFile))
    {
        xmlpatch.Patch(sourceDoc, diffgramReader);

        using (var writer = XmlWriter.Create(outputFile))
        {
            doc.Save(writer);
            output.Close();
        }

        reader.Close();
    }
}
