VBA 生成XML(转)

需要引用连个库，Microsoft ADO Ext. 6.0 for DDL and Security, Miscrosoft  ActiveX Data Objects 2.7 Library .

Sub 按钮2_Click()
    Dim xmlFile As String
    xmlFile = "D:	estooks.xml"
    CreateXml xmlFile
End Sub

Function CreateXml(xmlFile As String)
    Dim xDoc As Object
    Dim rootNode As Object
    Dim header As Object
    Dim newNode As Object
    Dim tNode As Object

    Set xDoc = CreateObject("MSXML2.DOMDocument")
    Set rootNode = xDoc.createElement("BookList")
    Set xDoc.DocumentElement = rootNode
    'xDoc.Load xmlFile
    Set header = xDoc.createProcessingInstruction("xml", "version='1.0' encoding='Unicode'")
    xDoc.InsertBefore header, xDoc.ChildNodes(0)

    Set newNode = xDoc.createElement("book")
    Set tNode = xDoc.DocumentElement.appendChild(newNode)
    tNode.setAttribute "type", "program"

    Set newNode = xDoc.createElement("name")
    Set tNode = xDoc.DocumentElement.ChildNodes.Item(0).appendChild(newNode)
    tNode.appendChild (xDoc.createTextNode("Thinking in Java"))

    Set newNode = xDoc.createElement("author")
    Set tNode = xDoc.DocumentElement.ChildNodes.Item(0).appendChild(newNode)
    tNode.appendChild (xDoc.createTextNode("Bruce Eckel"))

    Set newNode = xDoc.createElement("book")
    Set tNode = xDoc.DocumentElement.appendChild(newNode)
    tNode.setAttribute "type", "literature"

    Set newNode = xDoc.createElement("name")
    Set tNode = xDoc.DocumentElement.ChildNodes.Item(1).appendChild(newNode)
    tNode.appendChild (xDoc.createTextNode("边城"))

    Set newNode = xDoc.createElement("author")
    Set tNode = xDoc.DocumentElement.ChildNodes.Item(1).appendChild(newNode)
    tNode.appendChild (xDoc.createTextNode("沈从文"))

    Set newNode = Nothing
    Set tNode = Nothing

    Dim xmlStr As String
    xmlStr = PrettyPrintXml(xDoc)
    WriteUtf8WithoutBom xmlFile, xmlStr

    Set rootNode = Nothing
    Set xDoc = Nothing

    MsgBox xmlFile & "输出完成"

End Function

'格式化xml,带换行缩进
Function PrettyPrintXml(xmldoc) As String
    Dim reader As Object
    Dim writer As Object
    Set reader = CreateObject("Msxml2.SAXXMLReader.6.0")
    Set writer = CreateObject("Msxml2.MXXMLWriter.6.0")
    writer.indent = True
    writer.omitXMLDeclaration = True
    reader.contentHandler = writer
    reader.Parse (xmldoc)
    PrettyPrintXml = writer.Output
End Function

' utf8无BOM编码格式
Function WriteUtf8WithoutBom(filename As String, content As String)
    Dim stream As New ADODB.stream
    stream.Open
    stream.Type = adTypeText
    stream.Charset = "utf-8"
    stream.WriteText "<?xml version=" & Chr(34) & "1.0" & Chr(34) & _
                     " encoding=" & Chr(34) & "UTF-8" & Chr(34) & "?>" & vbCrLf
    stream.WriteText content

    '移除前三个字节（0xEF,0xBB,0xBF）
    stream.Position = 3

    Dim newStream As New ADODB.stream
    newStream.Type = adTypeBinary
    newStream.Mode = adModeReadWrite
    newStream.Open

    stream.CopyTo newStream
    stream.Flush
    stream.Close

    newStream.SaveToFile filename, adSaveCreateOverWrite
    newStream.Flush
    newStream.Close    
End Function
