如何在C＃中合并2个xmls？

标签： xml merge

我是C＃的新手，我正在尝试使用相同的方法合并两个XML文件。我试过了diff和patch程序集。但似乎没什么可锻炼的。我需要合并的2个Xml文件如下：

文件A是原始文件。具体如下：

<?xml version="1.0" encoding="utf-8"?>
<Dashboards xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <Dashboard name="A">
    <Controls>
      <Control>
        <DashboardControls>
          <DashboardControl name="b" structure="abc" Layout="true">
          <DashboardControl name="c" structure="abcd" Layout="true">
            <SubstituteBoards>
                <DashboardControl name="c" structure="abcd" Layout="true" />
                <DashboardControl name="d" structure="abcde" Layout="true"/>
              </SubstituteBoards>
            </DashboardControl >
            </DashboardControl >
        </DashboardControls>
      </Control>
    </Controls>
  </Dashboard >
  <Dashboard name="B">
    <Controls>
      <Control>
        <DashboardControls>
          <DashboardControl name="b" structure="abc" Layout="true">
            <SubstituteBoards>
              <DashboardControl name="d"  structure="abcde" Layout="true"/>
              <DashboardControls name="c" structure="abcd" Layout="true" />
            </SubstituteBoards>
          </DashboardControl >
        </DashboardControls>
      </Control>
    </Controls>
  </Dashboard >
</Dashboards >

文件B是文件，其中包含新节点和文件A中已存在的节点的混合。

文件B如下：

<?xml version="1.0" encoding="utf-8"?>
<Dashboards xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <Dashboard name="A">
    <Controls>
      <Control>
        <DashboardControls>
          <DashboardControl name="b" structure="abc" Layout="true">
          <DashboardControl name="b" structure="abc" Layout="true">
            <SubstituteBoards>
                <DashboardControl name="c" structure="abcd" Layout="true" />
                <DashboardControl name="d" structure="abcde" Layout="true"/>
                <DashboardControl name="b" structure="abc" Layout="true"/>
              </SubstituteBoards>
            </DashboardControl>
            </DashboardControl>
        </DashboardControls>
      </Control>
    </Controls>
  </Dashboard >
  <Dashboard name="B">
    <Controls>
      <Control>
        <DashboardControls>
          <DashboardControl name="b" structure="abc" Layout="true">
            <SubstituteBoards>
              <DashboardControl name="d"  structure="abcde" Layout="true"/>
              <DashboardControls name="c" structure="abcd" Layout="true" />
            </SubstituteBoards>
          </DashboardControl>
        </DashboardControls>
      </Control>
    </Controls>
  </Dashboard>
</Dashboards>

因此合并的文件应该是

 <?xml version="1.0" encoding="utf-8"?>
<Dashboards xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <Dashboard name="A">
    <Controls>
      <Control>
        <DashboardControls>
          <DashboardControl name="b" structure="abc" Layout="true">
          <DashboardControl name="b" structure="abc" Layout="true">
          <DashboardControl name="c" structure="abcd" Layout="true">
            <SubstituteBoards>
                <DashboardControl name="c" structure="abcd" Layout="true" />
                <DashboardControl name="d" structure="abcde" Layout="true"/>
                <DashboardControl name="b" structure="abc" Layout="true"/>
              </SubstituteBoards>
            </DashboardControl>
            </DashboardControl>
            </DashboardControl>
        </DashboardControls>
      </Control>
    </Controls>
  </Dashboard >
  <Dashboard name="B">
    <Controls>
      <Control>
        <DashboardControls>
          <DashboardControl name="b" structure="abc" Layout="true">
            <SubstituteBoards>
              <DashboardControl name="d"  structure="abcde" Layout="true"/>
              <DashboardControls name="c" structure="abcd" Layout="true" />
            </SubstituteBoards>
          </DashboardControl >
        </DashboardControls>
      </Control>
    </Controls>
  </Dashboard >
</Dashboards >

我尝试过的xml差异和补丁代码如下：

private void button1_Click(object sender, EventArgs e)
    {

        XmlWriter diffGramWriter = XmlWriter.Create(@"path of the diffgram  file to be created");
        GenerateDiffGram(@"Path of file A.xml", @"path of diffgram file.xml", diffGramWriter);
        PatchUp(@"Path of file A.xml", @"path of diffgram file.xml", @"Path of merged file created.xml");



    }
    public void GenerateDiffGram(string originalFile, string finalFile, XmlWriter diffGramWriter)
    {

        XmlDiff xmldiff = new XmlDiff();
        bool bIdentical = xmldiff.Compare(originalFile, @"Path of file B.xml", true, diffGramWriter);
        diffGramWriter.Close();
    }

    public void PatchUp(string originalFile, String diffGramFile, string OutputFile)
    {
        StringBuilder sb = new StringBuilder();
        XmlDocument sourceDoc = new XmlDocument(new NameTable());
        sourceDoc.Load(originalFile);
        XmlTextReader diffgramReader = new XmlTextReader(diffGramFile);
        XmlPatch xmlpatch = new XmlPatch();
        xmlpatch.Patch(sourceDoc, diffgramReader);
        XmlWriterSettings settings = new XmlWriterSettings { Indent = true };
        using (XmlWriter output = XmlWriter.Create(OutputFile, settings))
        {
            sourceDoc.Save(output);
        }

              }

}

}

有人可以帮我解释代码以完成合并任务吗？ 提前谢谢。

以下代码的工作原理除外，原始数据中包含重复的内容。那是对的吗？如果您有两个列表1）g 2）g，g：您希望合并列表包含g，g？

以下是您的要求示意图。我没有足够的信息来编写合并代码。看文件A＆＃34; A＆＃34;案例和文件B＆＃34; A＆＃34;案例的例子很模糊。在一个案例中，SubstituteBoards是＆＃34; b＆＃34;的孩子。另一种情况SubstituteBoards是＆＃34; c＆＃34;。

的孩子 
File A
A = b -> c -> SubstituteBoards {c,d}
B = b -> SubstituteBoards {d,c}
File B
A = b - > b -> SubstituteBoards {c,d,b}
B = b -> SubstituteBoards { d, c}

Results
A = b -> b -> c -> SubstituteBoards {c,d,b}
B = b -> SubstituteBoards {d,c}​
