利用XSLT来换XML的根_[XML教程]

　　首先觉得利用XSLT还能过滤一些东西，然后再发送回客户端，所以决定采用XSLT
　　然后就是尝试写一个换根的XSL，如下

大致意思是，解析一个XML中的所有结点及属性，如果非根就直接拷贝，否则就查看是否存在子结点及属性。具体资料请参照MSXML的SDK文档。

　　然后写一个函数，使得NEWNODENAME可以指定：

这段代码为VB.Net中的实现，ASP中实现时需要注意对象附值需要用Set，还有返回值的问题

Public Function ChangeXmlRootNodeName(ByRef oXml As MSXML2.DOMDocument, ByVal name As String) As String
If oXml Is Nothing Then
Return ""
End If
Dim sXslt As String
sXslt = "" & vbCrLf
sXslt = sXslt & "" & vbCrLf
sXslt = sXslt & "" & vbCrLf
sXslt = sXslt & vbCrLf
sXslt = sXslt & "" & vbCrLf
sXslt = sXslt & "<" & name & ">"" & vbCrLf"
sXslt = sXslt & " " & vbCrLf
sXslt = sXslt & "" & vbCrLf
sXslt = sXslt & "" & vbCrLf
sXslt = sXslt & vbCrLf
sXslt = sXslt & "" & vbCrLf
sXslt = sXslt & " " & vbCrLf
sXslt = sXslt & " " & vbCrLf
sXslt = sXslt & " " & vbCrLf
sXslt = sXslt & " "" & vbCrLf"
sXslt = sXslt & """ & vbCrLf"
sXslt = sXslt & vbCrLf
sXslt = sXslt & "" & vbCrLf

Dim oXsl As New MSXML2.DOMDocument
oXsl.async = False
oXsl.resolveExternals = False
oXsl.loadXML(sXslt)

Dim sXml As String

sXml = oXml.transformNode(oXsl)

sXml = AddXmlHeader(sXml)

　sXsl = Nothing

Return sXml
End Function

　　还有，当然你也可以实现生成那个XSL的XSL文件，这就要看你如何设计了。
