XML 文件结尾的问题
没看到XML 规范里怎么说XML 文件的结尾。按照习惯，文本文档的结尾是有Null 字符的。可是用winHex 看别的XML 多数没有Null 结束字符，有谁知道到底怎么处理。
[解决办法]
处理XML文件有专门的类型库：
Option Explicit'引用Microsoft XML类型库'7个文本框：TxtName.Text,txtSex.Text,txtBirthday.Text,txtAddress.Text,txtZip.Text,txtQQ.Text,txtHomepage.Text Private p_AppPath As String' 返回各个节点的值Private Function GetNodeValue(ByVal start_at_node As IXMLDOMNode, ByVal node_name As String, Optional ByVal default_value As String = "") As String Dim value_node As IXMLDOMNode Set value_node = start_at_node.selectSingleNode(".//" & node_name) If value_node Is Nothing Then GetNodeValue = default_value Else GetNodeValue = value_node.Text End IfEnd FunctionPrivate Sub LoadValues() Dim xml_document As DOMDocument Dim values_node As IXMLDOMNode ' 载入文件 Set xml_document = New DOMDocument xml_document.Load p_AppPath & "Personal.xml" If xml_document.documentElement Is Nothing Then Exit Sub End If '寻找节点 Set values_node = xml_document.selectSingleNode("个人信息") ' 读取各个节点的值 txtName.Text = GetNodeValue(values_node, "姓名", "???") txtSex.Text = GetNodeValue(values_node, "性别", "???") txtBirthday.Text = GetNodeValue(values_node, "出生日期", "???") txtAddress.Text = GetNodeValue(values_node, "地址", "???") txtZip.Text = GetNodeValue(values_node, "邮编", "???") txtQQ.Text = GetNodeValue(values_node, "QQ", "???") txtHomepage.Text = GetNodeValue(values_node, "个人主页", "???") Set xml_document = NothingEnd Sub' 保存现有的值Private Sub SaveValues() Dim xml_document As DOMDocument Dim values_node As IXMLDOMNode ' 建立XML文件 Set xml_document = New DOMDocument Set values_node = xml_document.createElement("个人信息") xml_document.appendChild values_node CreateNode values_node, "姓名", txtName.Text CreateNode values_node, "性别", txtSex.Text CreateNode values_node, "出生日期", txtBirthday.Text CreateNode values_node, "地址", txtAddress.Text CreateNode values_node, "邮编", txtZip.Text CreateNode values_node, "QQ", txtQQ.Text CreateNode values_node, "个人主页", txtHomepage.Text ' 保存XML文件 xml_document.save p_AppPath & "Personal.xml" Set xml_document = NothingEnd SubPrivate Sub CreateNode(ByVal parent As IXMLDOMNode, ByVal node_name As String, ByVal node_value As String) Dim new_node As IXMLDOMNode Set new_node = parent.ownerDocument.createElement(node_name) new_node.Text = node_value parent.appendChild new_nodeEnd SubPrivate Sub Form_Load() ' 获得程序运行目录 p_AppPath = App.Path If Right$(p_AppPath, 1) <> "\" Then p_AppPath = p_AppPath & "\" ' 加载值 LoadValuesEnd SubPrivate Sub Form_Unload(Cancel As Integer) ' 保存现有的值 SaveValuesEnd Sub
