如何使用 VBA 访问导入的 XML 中的特定值

Question

我有一个完整的 .pdf 表格（XFDF，XML），我正在将其导入 excel。目标是从 XML.

中获取该字段的 "Field Name" 和 "Value"

目前我可以通过使用一个简单的命令来获得 "Value"（下图中的蓝色重音）：

 list(4).text

我正在为如何存储 "Field Name" 而苦恼。在下图中，它是黄色突出显示的expression/value。

我尝试了以下变体，但无法正常工作。

List(4).Attributes(1).value

关于如何访问嵌套值的任何提示？

列表 -> 项目 (4) -> 属性 -> 项目 (1) -> 值

Answer 1

考虑 XPath，这是一种比遍历 .Item、.ChildNodes、.Attributes 和其他元素集合更具表现力的解析工具。此外，您在 XML 文档中有一个默认名称空间 xmlns="..."。要解决此问题，请将 pdf 之类的冒号分隔前缀分配给默认命名空间以访问其范围内的所有节点。以下是遍历树的嵌套级别的通用版本：

Set oXMLFile = CreateObject("MSXML2.DOMDocument") '''“Microsoft.XMLDOM”)
XMLFileName = FName
oXMLFile.Load XMLFileName

' TEMPORARILY DEFINE PREFIX FOR DEFAULT NAMESPACE
oXMLFile.setProperty "SelectionNamespaces", "xmlns:pdf='http://ns.adobe.com/xfdf/'"

' PRINT ALL THIRD NESTED LEVEL NODE VALUES
Set myList = oXMLFile.SelectNodes("/*/*/*")
For Each var In myList
    Debug.Print var.Text
Next var
' 2
' 3
' 1
' D:23440101
' D:13240101
' D:12340101

' PRINT ALL THIRD NESTED LEVEL ATTRIBUTES VALUES
Dim var as Variant
...
Set myList = oXMLFile.SelectNodes("/*/*/*/@*")
For Each var In myList
    Debug.Print var.Text
Next var
' 3 C_AQS_1
' 3 C_AQS_2
' 3 C_AQS_3
' 3 C_AYS_1
' 3 C_AYS_2
' 3 C_AYS_3

如果您需要访问索引值，您仍然可以对节点或属性值使用 XPath

' PRINT INDEXED NODE AND ATTRIBUTE
Set myList = oXMLFile.SelectNodes("/*/*/*")         ' MOVE TO SECOND NESTED LEVEL
Debug.Print myList(0).SelectSingleNode("*").Text
Debug.Print myList(0).SelectSingleNode("@*").Text
' 2
' 3 C_AQS_1

Debug.Print myList(1).SelectSingleNode("*").Text
Debug.Print myList(1).SelectSingleNode("@*").Text
' 3
' 3 C_AQS_2

Debug.Print myList(2).SelectSingleNode("*").Text
Debug.Print myList(2).SelectSingleNode("@*").Text
' 1
' 3 C_AQS_3

并在循环中

Dim var as Variant
...
For Each var In myList
    If Not var.SelectSingleNode("*") Is Nothing Then
        Debug.Print var.SelectSingleNode("*").Text
        Debug.Print var.SelectSingleNode("@*").Text
    End If
Next var
