我一直在努力使用 XmlComparsion 功能。我必须比较两个 Xml 的差异，然后以 TreeView 的方式显示它们。

我做了一些研究，发现 Google Diff Match Patch 库看起来正是我的比较部分所需要的。

https://github.com/google/diff-match-patch

我已将其实现如下

public List<Diff> DiffLineMode(string text1, string text2)
        {
            var a = base.diff_linesToChars(text1, text2);
            var lineText1 = a[0];
            var lineText2 = a[1];
            var lineArray = (IList<string>)a[2];
            var diffs = base.diff_main(lineText1.ToString(), lineText2.ToString(), false);
            base.diff_charsToLines(diffs, lineArray);

                  return diffs;
        }

现在，我需要一些帮助的最大挑战是将这种差异变成像对象一样的树视图。

我已经完成了一个树视图类，我在其中解析了比较使用的两个 Xml 文件

public class TreeViewModel
    {
        public long ID { get; set; }
        public string NodeName { get; set; }
        public string AbsolutPath { get; set; }
        public string Value { get; set; }
        public string Xml { get; set; }
        public int Operation { get; set; } = 2;
        public List<TreeViewModel> Children { get; set; }
        public Dictionary<string, string> Attributes { get; set; }
    }

现在我想做的是确保来自 TreeView 的操作与来自 DIffMatchPatch 的操作结果相匹配，但我的问题是 DiffMatchPatch 将 Xml 比较为字符串并且根本不将 Xml 视为节点树。结果是 2 个简单的 Xml 书籍文件。

在更“可读”的视图中看起来像这样

在此处输入图像描述

现在您可以看到，如果您有 2 个或更多节点差异，它们作为“孔差异”在内部“放置”在一起，这让我将其解析为类似树视图的对象非常棘手。

在这里您还可以看到 book997 是一本新书，但与 book103 的描述相同，它将考虑从 book 103 的描述开始并在 book997 的描述之前结束的“添加”文本。在某种程度上，我想将两个节点都更改为节点，但我不知道我可以使用什么来匹配特定的 TreeView 节点与差异的一部分或孔。

希望我说清楚了。我开始觉得我开始对 GoogleDiffMatchPatch 的需求非常错误，但在这一点上，我更难创建基于节点的自定义 xml 比较器。

编辑：还添加了从 XML 到 TreeView 的解析

 public TreeViewModel ToTreeView(XDocument xmlDocument)
        {
            var rootNode = xmlDocument.Root;

            return ParseNode(rootNode, 1);
        }

  private TreeViewModel ParseNode(XElement node, int parentId)
        {
            if (node.HasElements)
            {
                var index = 0;
                var children = new List<TreeViewModel>();
                bool hasChild = false;
                foreach (var element in node.Elements())
                {
                    children.Add(ParseNode(element, parentId * 10 + index, panoramaId));
                    index++;
                }

                var treeNode = new TreeViewModel
                {
                    Children = children,
                    Value = hasChild ? string.Empty : node.Value,
                    AbsolutPath = node.GetAbsoluteXPath(),
                    ID = parentId,
                    Xml = node.ToString(),
                    NodeName = node.Name.ToString(),
                    Attributes = node.GetAttributes()
                };
            }
            else
            {
                var treeNode = new TreeViewModel
                {
                    ID = parentId,
                    Value = node.Value,
                    AbsolutPath = node.GetAbsoluteXPath(),
                    NodeName = node.Name.ToString(),
                    Attributes = node.GetAttributes(),
                    Xml = node.ToString(),
                };
            }
        }
