求助！！！EXCEL导出为XML

[Jacky_0823]

本人欲用VB6做一个小工具，将EXECL电子表格中的某些列（动态挑选）导出到一个XML模版中，现在不知道如何下手做起，请各位高手指点，能有原代码更好。谢谢

用vb将word文档（或其他的二进制数据）生成xml文件并互相转换
1. 建立一个新的vb工程

2. 引用 Microsoft XML,版本 2.0 或以上

3. 在窗体form1上建立按钮 cmdCreateXML 和 cmdGetBinary

代码：

Option Explicit
Dim oDoc As DOMDocument
Dim DOCINPATH As String
Dim XMLOUTPATH As String
Dim DOCOUTPATH As String

Private Sub cmdCreateXML_Click()

Dim oEle As IXMLDOMElement
Dim oRoot As IXMLDOMElement
Dim oNode As IXMLDOMNode

DOCINPATH = App.Path & "\DocInput.doc"
XMLOUTPATH = App.Path & "\XmlOuput.xml"

Call ReleaseObjects

Set oDoc = New DOMDocument
oDoc.resolveExternals = True

' Create processing instruction and document root
Set oNode = oDoc.createProcessingInstruction("xml", "version='1.0'")
Set oNode = oDoc.insertBefore(oNode, oDoc.childNodes.Item(0))

' Create document root
Set oRoot = oDoc.createElement("Root")
Set oDoc.documentElement = oRoot
oRoot.setAttribute "xmlns:dt", "urn:schemas-microsoft-com:datatypes"

' Add a few simple nodes with different datatypes
Set oNode = oDoc.createElement("Document")
oNode.Text = "Demo"
oRoot.appendChild oNode

Set oNode = oDoc.createElement("CreateDate")
oRoot.appendChild oNode
Set oEle = oNode

' Use DataType so MSXML will validate the data type
oEle.dataType = "date"

oEle.nodeTypedValue = Now

Set oNode = oDoc.createElement("bgColor")
oRoot.appendChild oNode
Set oEle = oNode

' Use DataType so MSXML will validate the data type
oEle.dataType = "bin.hex"

oEle.Text = &HFFCCCC

Set oNode = oDoc.createElement("Data")
oRoot.appendChild oNode
Set oEle = oNode

' Use DataType so MSXML will validate the data type
oEle.dataType = "bin.base64"

' Read in the data
oEle.nodeTypedValue = ReadBinData(DOCINPATH)

' Save xml file
oDoc.save XMLOUTPATH

MsgBox XMLOUTPATH & " is created for you."

End Sub

Function ReadBinData(ByVal strFileName As String) As Variant
Dim lLen As Long
Dim iFile As Integer
Dim arrBytes() As Byte
Dim lCount As Long
Dim strOut As String

'Read from disk
iFile = FreeFile()
Open strFileName For Binary Access Read As iFile
lLen = FileLen(strFileName)
ReDim arrBytes(lLen - 1)
Get iFile, , arrBytes
Close iFile

ReadBinData = arrBytes
End Function

Private Sub WriteBinData(ByVal strFileName As String)
Dim iFile As Integer
Dim arrBuffer() As Byte
Dim oNode As IXMLDOMNode

If Not (oDoc Is Nothing) Then

' Get the data
Set oNode = oDoc.documentElement.selectSingleNode("/Root/Data")

' Make sure you use a byte array instead of variant
arrBuffer = oNode.nodeTypedValue

' Write to disk

iFile = FreeFile()
Open strFileName For Binary Access Write As iFile
Put iFile, , arrBuffer
Close iFile

End If

End Sub

Private Sub cmdGetBinary_Click()

DOCOUTPATH = App.Path & "\DocOutput.doc"

Set oDoc = New DOMDocument

If oDoc.Load(XMLOUTPATH) = True Then
' Save the Doc as another file
WriteBinData DOCOUTPATH

MsgBox DOCOUTPATH & " is created for you."
Else
MsgBox oDoc.parseError.reason
End If
End Sub

Private Sub Form_Unload(Cancel As Integer)
ReleaseObjects
End Sub

Private Sub ReleaseObjects()
Set oDoc = Nothing
End Sub

4. 建立word文档DocInput.doc.


5. 保存文档在工程目录下

6. 运行程序点击cmdCreateXML 按钮.一个 XML 文件XmlOuput.xml 就建立了.
点击 cmdGetBinary 按钮就可以生成word文档 DocOutput.doc.


按照上面的方法，同样可以将任意的二进制数据存为xml，然后再重新生成二进制数据

可以用于web传输等等可以使用xmlhttp的地方
