我有一个我试图解析的xml文件：

这是xml文件内容

这是代码：

Dim XDoc As Object

Set XDoc = CreateObject("MSXML2.DOMDocument")
XDoc.async = False: XDoc.validateOnParse = False
XDoc.Load (ThisWorkbook.Path & "\test.xml")

'Get Document Elements
Set lists = XDoc.DocumentElement

'Traverse all elements 2 branches deep
For Each listNode In lists.ChildNodes
    For Each fieldNode In listNode.ChildNodes
        Debug.Print "[" & fieldNode.BaseName & "] = [" & fieldNode.Text & "]"
    Next fieldNode
Next listNode

Set XDoc = Nothing

我正在使用或未在此行设置块获取对象变量：

For Each listNode In lists.ChildNodes

Answer 1

您的XML文件无法正确加载。

a）我认为您的XML文件以<?xml version="1.0" encoding="utf-8"?>之类的东西开头，因此可以将其标识为XML。

b）最好声明你的对象设置（总是在声明头中使用Option Explicit）。当您使用所谓的后期绑定时，只需编写如下：

Dim XDoc      As Object
Dim lists     As Object
Dim listNode  As Object
Dim fieldNode As Object

提示如果您使用Set XDoc = CreateObject("MSXML2.DOMDocument")将XDoc对象设置为内存，通常会获得旧版本（3.0），因此在大多数情况下，最好使用Set XDoc = CreateObject("MSXML2.DOMDocument.6.0")相反，它自动包含XPath。如果没有，您应按如下方式填写您的代码：

Set XDoc = CreateObject("MSXML2.DOMDocument")
XDoc.async = False: XDoc.validateOnParse = False
XDoc.setProperty "SelectionLanguage", "XPath"       ' << XPath functionality

c）您的XML文件未成功加载，因为它在 P Griffiths＆amp;中包含一个名为＆符号（“＆amp;”）的不可读字符。儿子和 Jo＆amp; hn ，必须更改为“&”。＆符号用作特殊字符的通用前缀，因此不能单独包含在文件中。您可以使用以下代码测试加载，而不是仅使用XDoc.Load (ThisWorkbook.Path & "\test.xml")：

If XDoc.Load(ThisWorkbook.Path & "\test.xml") Then
   MsgBox "Loaded successfully"
Else
  Dim xPE        As Object    ' Set xPE = CreateObject("MSXML2.IXMLDOMParseError")
  Dim strErrText As String
  Set xPE = XDoc.parseError
  With xPE
     strErrText = "Load error " & .ErrorCode & " xml file " & vbCrLf & _
     Replace(.URL, "file:///", "") & vbCrLf & vbCrLf & _
    xPE.reason & _
    "Source Text: " & .srcText & vbCrLf & vbCrLf & _
    "Line No.:    " & .Line & vbCrLf & _
    "Line Pos.: " & .linepos & vbCrLf & _
    "File Pos.:  " & .filepos & vbCrLf & vbCrLf
  End With
  MsgBox strErrText, vbExclamation
  Set xPE = Nothing
  Exit Sub
End If

d）顺便说一句，还有其他更完整的循环方式（递归调用）。当然你会在SO网站找到一些。

你的代码对我来说很好。作为@FlorentB。建议，该文件可能无法解析。我怀疑它们是文件名中的错误。添加一些错误处理将有助于捕获这些错误。

Sub PrintXML()

    Dim FilePath As String
    Dim XDoc As Object

    FilePath = ThisWorkbook.Path & "\test.xml"

    If Len(Dir(FilePath)) = 0 Then
        MsgBox "File not Found:" & vbCrLf & FilePath, vbCritical
        Exit Sub
    End If

    Set XDoc = CreateObject("MSXML2.DOMDocument")
    XDoc.async = False: XDoc.validateOnParse = False
    XDoc.Load ("C:\Users\norkiosk\Documents\Fax\test.xml")

    'Get Document Elements
    Set lists = XDoc.DocumentElement

    If lists Is Nothing Then
        MsgBox "Failed to Parse File:" & vbCrLf & FilePath, vbCritical
        Exit Sub
    End If

    'Traverse all elements 2 branches deep
    For Each listNode In lists.ChildNodes
        For Each fieldNode In listNode.ChildNodes
            Debug.Print "[" & fieldNode.BaseName & "] = [" & fieldNode.Text & "]"
        Next fieldNode
    Next listNode

    Set XDoc = Nothing

End Sub
