我几个月来一直在关注这个问题，我主要发现网站提出了同样的问题。
我发现的答案总是用于.NET或C或涉及XSLT。
经过几个月的研究，我已经提出了这一点。
Public Function PrettyPrintXML(XML As String) As String
Dim Reader As New SAXXMLReader60
Dim Writer As New MXXMLWriter60
Writer.indent = True
Writer.standalone = False
Writer.omitXMLDeclaration = False
Writer.encoding = "utf-8"
Set Reader.contentHandler = Writer
Set Reader.dtdHandler = Writer
Set Reader.errorHandler = Writer
Call Reader.putProperty("http://xml.org/sax/properties/declaration-handler",_
Writer)
Call Reader.putProperty("http://xml.org/sax/properties/lexical-handler",_
Writer)
Call Reader.parse(XML)
PrettyPrintXML = Writer.output
End Function
使用文档：
Public Function PrettyPrintDocument(Doc As DOMDocument60) As String PrettyPrintDocument = PrettyPrintXML(Doc.XML) End Function
