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

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
