Append on VB.net

Hi Experts

I inputting values in a xml but I am only getting one row. Can I have some assistance to extract all row

Mu current output look like this

<?xml version="1.0"?>
<transferupload>
            <transfer>
                  <Currency>USD</Currency>
                  <Legal Entity>IBL ICM COLLATERAL</Legal Entity>
                  <Accountid>1038</Accountid>
                  <Movement>-118698</Movement>
                  <Value Date>2/1/2011 12:00:00 AM</Value Date>
                  <Narration>Collateral call</Narration>
                  <Counterparty>INBOUND_SWIFT</Counterparty>
            </transfer>
</transferupload>

But I need it to look like this depending on the rows that I am extracting

<?xml version="1.0"?>
<transferupload>
            <transfer>
                  <Currency>USD</Currency>
                  <Legal Entity>IBL ICM COLLATERAL</Legal Entity>
                  <Accountid>1038</Accountid>
                  <Movement>-118698</Movement>
                  <Value Date>2/1/2011 12:00:00 AM</Value Date>
                  <Narration>Collateral call</Narration>
                  <Counterparty>INBOUND_SWIFT</Counterparty>
            </transfer>
            <transfer>

                  <Movement>-1186981</Movement>
                  <Value Date>2/1/2011 12:00:00 AM</Value Date>
                  <Narration>Collateral call</Narration>
                  <Counterparty>INBOUND_SWIFT_New</Counterparty>
            </transfer>

where (how) are you getting the data?

You need to iteratethe datasource to include the second item.

ASKER

from an Excel source Which is stored in "Row"

nepaluz

So how are you connecting to the excel file (or is it a plain csv file that you read using VB.net)?

You'll need to show some code of how you are reading the file.

I am doing this in SSIS using an Excel Source and then connecting to a Script Component and the VB code is in the Script Component

not sure how you are getting the data, but here is a working example of what I meant you should you.

        'first declare your root element
        Dim xNew As XElement = New XElement("transfer")
        'some test data in a list of string
        Dim TestData As New List(Of String) From {"USD IBL 1038 -118 2/1/2011 Collateral Inbound", "USD IBL 1039 -118 3/1/2011 Collateral Outbound"}
        'then iterate through the source here to call the function
        For Each x As String In TestData
            Dim Res = x.Split(" ")
            xNew.Add(ProcXML(Res(0), Res(1), Res(2), Res(3), Res(4), Res(5), Res(6)))
        Next
        Dim s As XmlSerializer = New XmlSerializer(xNew.GetType)
        Using w As New XmlTextWriter("Path", System.Text.Encoding.UTF8)
            w.Formatting = Formatting.Indented
            s.Serialize(w, xNew)
        End Using

Open in new window

The above code callthe following function

    Public Function ProcXML(ByVal Currency As String, ByVal Entity As String, ByVal AccountID As String, _
                            ByVal Movement As String, ByVal ValueDate As String, ByVal Narration As String, _
                            ByVal CounterParty As String) As List(Of XElement)

        Dim CurELE As XElement = New XElement("Currency", Currency)
        Dim EntELE As XElement = New XElement("Legal Entity", Entity)
        Dim ActELE As XElement = New XElement("Accountid", AccountID)
        Dim MovELE As XElement = New XElement("Movement", Movement)
        Dim ValELE As XElement = New XElement("Value Date", ValueDate)
        Dim NarELE As XElement = New XElement("Narration", Narration)
        Dim CouELE As XElement = New XElement("Counterparty", CounterParty)
        'if you areusing .NET 4.0 you can use this else add to the list per usual
        Dim returnList As New List(Of XElement) From {CurELE, EntELE, ActELE, MovELE, ValELE, NarELE, CouELE}
        Return returnList

    End Function

Open in new window

In your example code, the Sub simply gets ONE element and writes it to disk. There is not iterating through a series of data to achieve what you want. I have tried to get some dummy data for you and elaborate the iteration that is missing from your code, hope it makes sense.

1. The code you have given could NOT have written the file you attached. All the elements in your code are empty.

2. The elements in your code (just like in my code) are INVALID and thus you will get errors if you try to use the code as is.

For my code, you will have to replace all elements with spaces in their names with an underscore. If you areeagle eyed, you will have noticed that the imagein my XML file has these elements' names chaged, e.g Value Date changed to Value_Date etc ... In code, the culprit would be

        'change this
        Dim ValELE As XElement = New XElement("Value_Date", ValueDate)

        'to this
        Dim ValELE As XElement = New XElement("Value_Date", ValueDate)

Open in new window

Because of the errors in your XML file, I can NOT auto open it using the default viewer (in my case Explorer).

Finally, your code makes use of a class named UserComponent. This may contain the iteration routine that you need to examine. Having said that, though, the resulting XML will not meet your requirements, because liske I mentioned, all the elements in your routine are BLANK / EMPTY!

Hi

I am try to understand how to apply the code to my ENV as I am not fully understanding VB.net

'first declare your root element
        Dim xNew As XElement = New XElement("transferupload")
        'some test data in a list of string
        Dim TestData As New List(Of String) From {"USD IBL 1038 -118 2/1/2011 Collateral Inbound", "USD IBL 1039 -118 3/1/2011 Collateral Outbound"}
        'then iterate through the source here to call the function
        For Each x As String In TestData
            Dim Res = x.Split(" ")
            xNew.Add(New XElement("transfer", ProcXML(Res(0), Res(1), Res(2), Res(3), Res(4), Res(5), Res(6))))
        Next
        Dim s As XmlSerializer = New XmlSerializer(xNew.GetType)
        Using w As New XmlTextWriter("C:\NewFile.xml", System.Text.Encoding.UTF8)
            w.Formatting = Formatting.Indented
            s.Serialize(w, xNew)
        End Using




 Public Function ProcXML(ByVal Currency As String, ByVal Entity As String, ByVal AccountID As String, _
                            ByVal Movement As String, ByVal ValueDate As String, ByVal Narration As String, _
                            ByVal CounterParty As String) As List(Of XElement)

The code I gave you should be adequate to write the XML that you wish to write using the test data. A little tweaking to incorporate your data loading routine is all it requires. However, since you are not willing to divulge how you call the routine, I am un-abe to suggest a solution for that code.
