Question

我希望在节点中找到相同值时合并节点，并且检查值是顺序还是不是

请检查以下几点：

1）如果code-id标签值是顺序方式且主题标签值相同则合并节点。

2）如果code-id标签值是顺序方式但主题标签值是diff，则避免合并。

3）如果code-id标签值不是序列化但主题标签值相同则避免合并。

4）如果code-id标签值不是序列化的，但主题标签值是diff，则避免合并。

您能否告诉我如何获得所需的输出？

提前致谢。

我的代码：

 XDocument xDoc = XDocument.Parse(xmlstr);
            XElement xElementSelectRoot = xDoc.XPathSelectElement("//root");

            XElement xElementCreateRoot = new XElement(new XElement("root"));

            IEnumerable<XElement> lstOFCatogory = xElementSelectRoot.XPathSelectElements("//category").OrderBy(r => r.Value).ToList();

            foreach (var varXNodeCategory in lstOFCatogory)
            {
                if (varXNodeCategory.Parent.Name == "Product")
                {
                    XmlDocument xmlDoc = new XmlDocument();
                    xmlDoc.LoadXml(varXNodeCategory.Parent.ToString());
                    XmlNodeList xmlNodeCategoryList = xmlDoc.SelectNodes("//category");

                    XmlDocument xmlDoc1=new XmlDocument();
                    xmlDoc1.LoadXml(varXNodeCategory.ToString());

                    XmlNode xmlNodeSelectCategory = xmlDoc1.SelectSingleNode("//category");
                    foreach (XmlNode xmlNode in xmlNodeCategoryList)
                    {
                        xmlNode.ParentNode.RemoveChild(xmlNode);
                        if (xmlNode.FirstChild.InnerText.Equals(xmlNodeSelectCategory.FirstChild.InnerText))
                        {
                            xmlNodeSelectCategory = xmlNode;
                        }
                    }
                    xmlDoc.LastChild.AppendChild(xmlNodeSelectCategory);
                    XmlNode xmlNode1 = xmlDoc.SelectSingleNode("//Product");

                    var varXElement= XElement.Parse(xmlDoc.InnerXml);

                    xElementCreateRoot.Add(varXElement);
                }
                else
                {
                    xElementCreateRoot.Add(varXNodeCategory);
                }
            }

Answer 1

我得到了解决方案，现在工作正常。

        XDocument xmlDocNew = XDocument.Parse(xElementCreateRoot.ToString());
        XElement xElementSelectRootNew = xmlDocNew.XPathSelectElement("//root");
        XElement xElementCreateRootNew = new XElement(new XElement("root"));
        IEnumerable<XElement> lstOFCatogoryNew = xElementSelectRootNew.XPathSelectElements("//category").OrderBy(r => r.Value).ToList();
        List<Class1> lstClass1 = new List<Class1>();
        int intClassIndexCounter = 0;
        foreach (var x in lstOFCatogoryNew)
        {
            if (x.Parent.Name.ToString() == "Product")
            {
                if (lstClass1.Count() > 0)
                {
                    if (lstClass1[lstClass1.Count()-1].SujectName.Trim().ToString() == ((XElement)x.Parent.FirstNode).Value.Trim().ToString())
                    {

                        var xsDoc = new XDocument(new XElement(XElement.Parse(x.Parent.ToString())));

                        XElement xElementSelectProduct = xsDoc.XPathSelectElement("//Product");

                        xElementCreateRootNew.Elements("Product").Last().Add(xElementSelectProduct.XPathSelectElement("//category"));


                        lstClass1.Add(new Class1(((XElement)x.Parent.FirstNode).Value.Trim().ToString(),//subject title
                            ((XElement)x.FirstNode).Value.Trim().ToString(),//code-id
                            x.Parent.ToString().Trim()));//product set

                        intClassIndexCounter++;
                    }
                    else
                    {
                        xElementCreateRootNew.Add(x.Parent);
                        lstClass1.Add(new Class1(((XElement)x.Parent.FirstNode).Value.Trim().ToString(),//subject title
                            ((XElement)x.FirstNode).Value.Trim().ToString(),//code-id
                            x.Parent.ToString().Trim()));//product set

                        intClassIndexCounter++;
                    }
                }
                else
                {
                    xElementCreateRootNew.Add(x.Parent);
                    lstClass1.Add(new Class1(((XElement)x.Parent.FirstNode).Value.Trim().ToString(),//subject title
                        ((XElement)x.FirstNode).Value.Trim().ToString(),//code-id
                        x.Parent.ToString().Trim()));//product set

                    intClassIndexCounter++;
                }
            }
            else
            {
                xElementCreateRootNew.Add(x);
            }
        }
