如何使用C＃在XML文件中查找缺失值

How to find missing values in XML file using C#

<Model>
<Component Id="1"><Color></Color>
<Component Id="2"><Color></Color>
<Component Id="2"><Color></Color>
<Component Id="4"><Color></Color>
<Component Id="5"><Color></Color>
<Component Id="6"><Color></Color>
<Component Id="6"><Color></Color>
<Component Id="8"><Color></Color>
<Component Id="9"><Color></Color>
</Model>

在上面的XML代码中重复Id =2和Id =6。

我想从序列中找出缺失值。

我必须用以下内容替换重复值最近的可能值



例如：



输出应该是：

IN the above XML code Id="2" and Id="6" is repeated.
Do I want to find out the missing values from sequence.
I have to replace the repeated values with nearest possible values

Example:

The Output should be:

<Model>
<Component Id="1"><Color></Color>
<Component Id="2"><Color></Color>
<Component Id="3"><Color></Color>
<Component Id="4"><Color></Color>
<Component Id="5"><Color></Color>
<Component Id="6"><Color></Color>
<Component Id="7"><Color></Color>
<Component Id="8"><Color></Color>
<Component Id="9"><Color></Color>
</Model>

我有什么方法可以使用C＃

I there any way to solve this problem using C#

推荐答案

解决这个问题请参考下面的代码，我为组件标签添加了结束标签： -

Please refer following code, i have added closing tags for Component tags:-

string szXML = "<Model>" +
                           "<Component Id='1'><Color></Color></Component>" +
                           "<Component Id='2'><Color></Color></Component>" +
                           "<Component Id='2'><Color></Color></Component>" +
                           "<Component Id='4'><Color></Color></Component>" +
                           "<Component Id='5'><Color></Color></Component>" +
                           "<Component Id='6'><Color></Color></Component>" +
                           "<Component Id='6'><Color></Color></Component>" +
                           "<Component Id='8'><Color></Color></Component>" +
                           "<Component Id='9'><Color></Color></Component>" +
                        "</Model>";

           XmlDocument objDOM = new XmlDocument();
           objDOM.LoadXml(szXML);//you can specify file name here
           for (int iIndex = 0; iIndex < objDOM.DocumentElement.ChildNodes.Count; iIndex++)

           {

               objDOM.DocumentElement.ChildNodes[iIndex].Attributes["Id"].Value = (iIndex + 1).ToString();

           }

           //objDOM.Save(szFileName) //if xml loaded from File
