[无聊扔作业系列]（二）一个简单的XML浏览/编辑器

题目：

引用

第三章实践作业

1.编写一个窗口应用程序，在窗口中有一个Tree控件和一个“浏览”按钮。单击“浏览”按钮，可以打开一个“打开文件”对话框，选择一个XML文件，在Tree中显示XML所对应的树形结构。
2.扩展创新功能（可选的附加功能，属加分项目）：对树结构的处理上，例如添加、删除节点。能保存到原XML文件中。

作业要求：
窗口应用程序  
功能：
单击按钮——弹出文件选择框——选取XML文件——显示XML文件的树形结构
会用到的控件：Tree控件。

作业涉及的代码内容：

• Button以及它的事件响应，调用文件选择对话框。
• OpenFileDialog类，以及其中部分方法，属性。（主要使用该类中获取文件地址相关的一些属性和方法）
• XmlNode和XmlDocument类（用DOM浏览XML）
• TreeView类：将DOM中的节点传递到TreeView节点中，实现方法因人而异，像数据结构中的访问树节点，也可以用递归实现。一种递归函数实现方法是：将XmlNode和TreeNodeCollection对象作为参数

开发环境：
Visual Studio 2008 Beta 2 / .NET Framework 3.5 Beta 2
.NET Framework最低必需版本：3.5

===============================================================

这次的作业要求也很straight forward。最核心的部分应该就在于XML树形结构的遍历了吧。
这里我采用了递归的深度优先搜索来遍历XML文件。
遍历部分的代码如下，XMLTraverse()：

public void XMLTraverse<T>( XmlNode root, T obj, Action<XmlNode, T> action, MoveNext<T> moveNext ) {
    // do something else with currentNode here
    if ( action != null ) {
        action( root, obj );
    }
    
    // recurse predicate
    if ( root.NodeType == XmlNodeType.Element ) {
        // traverse direct children of current node
        XmlNodeList list = root.ChildNodes;
        foreach ( XmlNode node in list ) {
            T nextobj;
            if ( moveNext != null ) {
                nextobj = moveNext( obj );
            } else {
                nextobj = obj;
            }
            XMLTraverse( node, nextobj, action, moveNext );
        }
    }
}

可以看到，这里只定义了遍历一个XML树形结构算法的骨架，却没有把具体要遍历来做什么（action）给写死在里面。
用到了.NET Framework标准库里的一个delegate类型Action<T1, T2>和自定义的一个delegate类型MoveNext<T>，它们的signature分别如下：

public delegate void Action<T1, T2>( T1 t1, T2 t2 );
public delegate T MoveNext<T>( T collection );

Action<T1, T2>指向返回类型为void的方法，用于指定遍历时的动作；MoveNext<T>指向返回类型为T的方法，指定如何将当前集合移动要下一个集合。本来应该用IEnumerable之类的接口更好的，但这里没想出什么好办法来实现，罢了。
（这里有个很明显的死循环bug：如果moveNext参数是null的话，这函数基本上就要死循环了……不过也要看action里到底怎么用。所以就先这么放着了。以后想清楚了再改）

应用这个遍历函数的是PopulateXmlTreeView()：

private void PopulateXmlTreeView( XmlNode node, TreeNodeCollection tnodes ) {
    this.xmlTreeView.BeginUpdate( );
    // traverse  an XML tree and fill in the xmlTreeView
    XMLTraverse(
        node,
        tnodes,
        ( xmlnode, treeNodeCol ) => {
            if ( xmlnode.NodeType == XmlNodeType.Element ) {
                // add the element to xmlTreeView
                TreeNode n = new TreeNode( xmlnode.Name );
                n.Tag = xmlnode; // tag the TreeNode with current xml node
                treeNodeCol.Add( n );
            } else {
                TreeNode n = new TreeNode( xmlnode.Value.Trim( ) );
                n.Tag = xmlnode; // tag the TreeNode with current xml node
                treeNodeCol.Add( n );
            }
        },
        collection => collection[ collection.Count - 1 ].Nodes );

    this.xmlTreeView.EndUpdate( );
}

在PopulateXmlTreeView()方法里，指定了XMLTraverse()该具体在遍历时做些什么——这里是将XML节点的信息加入一个TreeView中。注意到这里也应用到了Lambda Expression及相关的类型推断，这两项都是C# 3.0新增的利器。

核心逻辑解决了，开始做界面。打开Visual Studio 2008，新建project，并在designer里拖出界面，如下：

        private string currentFilePath;

    }
}

为了实现编辑功能，还另外加了一个非常简单的Form来做文本插入，
InsertElementForm.cs：

using System;
using System.Windows.Forms;

namespace XMLTreeView
{
    public partial class InsertElementForm : Form
    {
        public event EventHandler ElementOk;

        public string InsertContent {
            get {
                return this.txtContent.Text;
            }
        }

        public InsertElementForm( ) {
            InitializeComponent( );
        }

        private void OnElementOk( EventArgs e ) {
            EventHandler handler = this.ElementOk;
            if ( handler != null ) {
                handler( this, e );
            }
        }

        private void btnOk_Click( object sender, EventArgs e ) {
            if ( this.txtContent.Text == null || this.txtContent.Text.Length == 0 ) {
                return;
            }

            OnElementOk( new EventArgs( ) );
        }
    }
}

到此，实现的功能有（以下内容来自交作业时的readme）：

.NET程序设计 第三章上机作业

==============================================

Revision 1

界面如rev_screenshot.jpg所示。左上角是作业所要求的TreeView，用于显示XML文件的树形结构。左下角的ListView用于显示TreeView中当前选定节点中的Attribute列表，不可选中。右侧的TextBox用于显示TreeView中当前选定节点的整个内容（包括其子节点的内容），可以用于编辑当前节点的内容。

要编辑当前节点内容，需先确保在左侧的TreeView中选定了节点，然后在右侧的TextBox中修改内容，并点击“Commit”按钮（工具条中左起第三个），或选用菜单->Edit->Commit Edit

要插入新节点，需先确保在左侧的TreeView中选定了节点，然后点击“Insert”按钮（工具条中左起第四个）或选用菜单->Insert Element->...，在弹出的对话框中输入插入的内容，按对话框右下角的“Insert”按钮确定。注意：无法在根节点的前后插入新节点，也无法在文字节点或注释等非Element节点下添加子节点。

要删除一个节点，需先确保在左侧的TreeView中选定了节点，并点击“Delete”按钮（工具条中左起第五个）或选用菜单->Edit->Delete Element。

界面如screenshot.jpg所示。左上角是作业所要求的TreeView，用于显示XML文件的树形结构。左下角的ListView用于显示TreeView中当前选定节点中的Attribute列表。右侧的TextBox用于显示TreeView中当前选定节点的整个内容（包括其子节点的内容）。

已完成的功能有：显示一个XML文件（树形、文字），删除节点，保存修改（到原XML文件或到新文件）。
待完成的功能有：编辑、添加节点。（代码框架已完成，但两处实现细节尚未编码，于是留空）

TreeView、ListView与TextBox之间的分隔可拖动。工具条也可拖动挂靠到上、左、右三侧（禁用了下侧）。

注意：该代码使用了.NET Framework 3.0或以上才支持的delegate Action<T1, T2>，因此无法在.NET Framework 2.0上编译运行。

这些designer生成的代码要是手写的话肯定痛苦死了……呼。

All right，大功告成 ^ ^
如果还有什么药补充的话，应该就是：为了偷懒，我没有直接用DOM去操纵XML的编辑，而是通过.NET Framework的一个扩展——XPathNavigator来帮忙。这样效率虽说不太高，不过节省了很多手工的调用……诶总之算不上什么好办法就是了 =_=||

我觉得这次应该已经比系列的上一篇好一些了?
因为只要是跟GUI相关的东西,代码都未必"好看"到哪里去.
Designer生成的都是...怎么说,垃圾代码? 或者温和点说,是有存在的必要但却不想手写的代码.所以这次把designer生成的代码都放在最后了...
然后也把其中最有用的代码放在前面说了...
-
或许应该把编译出来的exe也一起放出来? 直接使用的话心情会轻松很多 XD
写了这作业之后,自己也偶尔会用这程序...不过更多的时候还是直接开UEStudio来编辑了

感觉一堆很复杂的CODE－ －眼睛麻麻的～

还是建议选择一些有趣的绍介〇〇
