如何将多个 XML 中的值提取到 Excel 中？

Question

我有大量的 XML 都是这种形式的松散形式（有些有不同数量的字段，但都包含我想要的某些信息）

<message>
  <stdHeader> don't want </stdheader>
  <formdata>
     <field1>
        <subfield1>
            <type> don’t want </type>
            <name> want </name>
        </subfield1>
        <subfield2> want </subfield2>
        <subfield3> don't want </subfield4>
    </field1>
    <field2> don't want  </field2>
    <field3>
        <subfield1>
            <givenName> want  </givenName>
            <familyName> want  </familyName>
    </field3>
 </formdata>
 <aaaa>don't want </aaaa>  
 <bbbb>don't want</bbbb>  
 <cccc>don't want</cccc>  
 <dddd>don't want</dddd>  
 <eeee>don't want</eeee>  
 <ffff>don't want</ffff>  
</message>

我想要一个列标题为“name”、“subfield3”、“givenName”、“familyName”（来自上面）的表格，每行都有来自每个 XML 的这些值。我是一个编程初学者，所以我不知道如何 1. 仅从单个 xml 中提取我想要的值 2. 编写一些代码来执行 1. 为文件夹中的每个 XML 文件。谁能帮帮我？

Answer 1

这个子遍历文件夹中的所有文件，如果找到任何 XML，它会调用第二个子

---

Option Explicit

'in code editor: Tools > References > checkbox in Microsoft Scripting Runtime

Public Sub ProcessXMLs()
    Const FOLDER_NAME   As String = "C:\Tmp"        '<- update this path

    Dim tags As Variant, hdrs As Variant, rowID As Long
    Dim fso As FileSystemObject, f As File

    Set fso = New Scripting.FileSystemObject

    hdrs = Array("FileName", "ItemID", "Name", "GivenName", "FamilyName")
    tags = Array("FileName", "value", "name", "givenNames", "familyName")

    With Sheet1
        .Range(.Cells(1, 1), .Cells(1, UBound(tags) + 1)).Value2 = hdrs
        rowID = 2
        Application.ScreenUpdating = False
        For Each f In fso.GetFolder(FOLDER_NAME).Files   'iterate through files
            If LCase(fso.GetExtensionName(f)) = "xml" Then
                .Cells(rowID, 1).Value2 = fso.GetBaseName(f) & ".xml"
                ReadTags Sheet1, fso.OpenTextFile(f.Path, ForReading), rowID, tags
                rowID = rowID + 1
            End If
        Next
        .UsedRange.Columns.AutoFit
        Application.ScreenUpdating = True
    End With
End Sub

这个子提取4个标签中的值，一次一个文件：

Private Sub ReadTags(ByVal ws As Worksheet, ByVal fsoFile As TextStream, _
                     ByVal rowID As Long, ByVal tags As Variant)

    Dim ln As String, val As String, i As Long, s1 As Long, s2 As Long

    With fsoFile
        Do While Not .AtEndOfStream       'file stream is open

            ln = Trim(.ReadLine)          'read each line

            If Len(ln) > 0 Then           'if text line is not empty extract tags
                For i = 1 To UBound(tags) 'find each tag - start and closing
                    s1 = InStr(1, ln, "<" & tags(i), 0)
                    s2 = InStr(s1 + 1, ln, "</" & tags(i) & ">", 0)
                    If s1 > 0 And s2 > 0 Then
                        s1 = InStr(s1, ln, """>", 0) + 2
                        ws.Cells(rowID, i + 1).Value2 = Trim(Mid(ln, s1, s2 - s1))
                        Exit For
                    End If
                Next
            End If
        Loop
    End With
End Sub

结果：
