如何在不是有效 xml 文件的文本文件的某些位置添加给定节点 ( <sec> ) 的结束节点。我知道这有点令人困惑，但这是 sample input text这是它的 desired output

基本上程序应该生成</sec>下一个 <sec> 之前的节点节点和多少 </sec>它是否会添加到所需位置取决于属性 id节点 <sec>使用由 . 分隔的数字如下:

如果下<sec>节点后说，<sec id="4.5">是<sec id="5">然后 2 </sec>应在 <sec id="5"> 之前添加

如果下<sec>节点后说，<sec id="3.2.1.2">是<sec id="3.4">然后 3 </sec>应在 <sec id="3.4"> 之前添加节点

显然我不能使用任何 xml 解析方法来做到这一点，还有什么其他方法可以做到这一点......我现在一无所知......谁能帮忙？示例输入

最佳答案

为了完成这个任务，我定义了一个额外的方法，它将返回多少结束标签</sec>应根据 ID 的不同插入:

public static int HowManyClosingTags(string startTagId, string endTagId)
{
   // if IDs are the same, then we don't need any closing tags
   if(startTagId == endTagId )
      return 0;
   // if following ID is subsection of previous tag section, then we don't need any closing tags
   if (endTagId.IndexOf(startTagId) == 0)
      return 0;

   int i = 0;
   while (startTagId[i] == endTagId[i])
      i++;

   return startTagId.Substring(i).Count(ch => ch == '.') + 1;
}

我使用字符串，因为它是无效的 XML，不能作为一个加载(XmlDocument.Load() 方法在无效 XML 的情况下抛出异常)。所以我正在对字符串进行基本操作(我希望这在代码中是可以理解的，我还包含了尽可能多的注释以使其清楚)。下面是代码:

static void Main(string[] args)
{
    string invalidXml = "your invalid XML";
    int closeTagPos = -1;
    int openTagPos = -1;
    string openTagId = "";
    string closeTagId = "";
    int howManyClosingTagsAlready;
    int lastPos;
    int howManyTagsToInsert;
    while (true)
    {
        //get indexes of opening tag and close tag, break, if none is found
        if((openTagPos = invalidXml.IndexOf("<sec id=\"sec", openTagPos + 1)) == -1)
            break;
        if((closeTagPos = invalidXml.IndexOf("<sec id=\"sec", openTagPos + 1)) == -1)
            break;
        //get the IDs of tags
        openTagId = invalidXml.Substring(
            openTagPos + 12,
            invalidXml.IndexOf('"', openTagPos + 12) - openTagPos - 12
        );
        closeTagId = invalidXml.Substring(
            closeTagPos + 12,
            invalidXml.IndexOf('"', closeTagPos + 12) - closeTagPos - 12
        );
        //count how many tags were already closed
        howManyClosingTagsAlready = 0;
        lastPos = invalidXml.IndexOf("</sec>", openTagPos);
        while (lastPos > -1 && lastPos < closeTagPos)
        {
            howManyClosingTagsAlready++;
            lastPos = invalidXml.IndexOf("</sec>", lastPos + 1);
        }

        howManyTagsToInsert = HowManyClosingTags(openTagId, closeTagId) - howManyClosingTagsAlready;
        for (int i = 0; i < howManyTagsToInsert; i++)
        {
            //insert closing tags
            invalidXml = invalidXml.Insert(closeTagPos, "</sec>");
        }
    }
    //now we have to close our last "unclosed" tag, in this case
    //</body> is treated as colsing tag, the logic stays the same
    openTagId = invalidXml.Substring(
        openTagPos + 12,
        invalidXml.IndexOf('"', openTagPos + 12) - openTagPos - 12
    );
    closeTagPos = invalidXml.IndexOf("</body>");
    howManyClosingTagsAlready = 0;
    lastPos = invalidXml.IndexOf("</sec>", openTagPos);
    while (lastPos > -1 && lastPos < closeTagPos)
    {
        howManyClosingTagsAlready++;
        lastPos = invalidXml.IndexOf("</sec>", lastPos + 1);
    }

    howManyTagsToInsert = openTagId.Count(ch => ch == '.') + 1 - howManyClosingTagsAlready;

    for (int i = 0; i < howManyTagsToInsert; i++)
    {
        //insert closing tags
        invalidXml = invalidXml.Insert(closeTagPos, "</sec>");
    }

    XmlDocument xml = new XmlDocument();
    xml.LoadXml(invalidXml);
}
