我正在尝试从xml银行对帐单中提取数据，稍后再将其转换为csv。
我想找到债权人的银行号码，在这里：
<Document xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:iso:std:iso:20022:tech:xsd:camt.053.001.02">
<BkToCstmrStmt>
<Stmt>
<Ntry>
<NtryDtls>
<TxDtls>
<RltdPties>
<CdtrAcct>
<Id>
<IBAN>DE1234567891012345</IBAN>
我正在使用以下代码：
Imports System.Xml
Imports System.Xml.Linq
Imports System.IO
Public Class Form1
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim doc As XDocument = XDocument.Load("bank_statement.xml")
Dim elements As IEnumerable(Of XElement)
Dim currentElement As XElement
elements = doc.Descendants()
For Each element As XElement In elements
If element.Name.LocalName.ToString() = "CdtrAcct" Then
currentElement = element.Descendants()
If currentElement.Name.LocalName.ToString() = "Id" Then
currentElement = currentElement.Descendants()
If currentElement.Name.LocalName.ToString() = "IBAN" Then
My.Computer.FileSystem.WriteAllText("bank_statement_csv.csv", currentElement.Value.ToString, True)
End If
End If
End If
Next
End Sub
End Class
我有问题，因为它们不是同一类，而且我不知道如何正确声明它
Dim elements As IEnumerable(Of XElement)
Dim currentElement As XElement
element As XElement In elements
您能给我一些诗人，如何解决这个问题？
