Question

我需要使用SSIS包将一些数据从XML文件导入到SQL Server，但是当我生成xsd文件（来自SSIS）时，XML文件中的一些必要数据不会映射为要输出的列：

这是我正在使用的一个非常相似的xml文件模型：

xml format model

需要导入第2行中的数据（DocumentID，ExportID，JobID，RunID，CreationTime，StartTime，EndTime）。

以下是从SSIS生成XSD文件的方法：

<?xml version="1.0"?>

我是SSIS和XML任务的新手，我将不胜感激任何帮助！ TKS ...

我认为您无法使用XML Source组件实现此目的，您必须添加脚本组件（作为源），打开脚本组件编辑器，添加所需的输出列（DocumentID，ExportID），JobID，RunID，CreationTime，StartTime，EndTime）。

然后打开脚本编辑器并编写以下代码（我使用VB.NET）：

您必须将"C:\MyPath\xmlfile.xml"替换为xml文件路径，您还必须添加System.Xml.Linq dll作为参考

Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper
Imports System.Xml
Imports System.Xml.Linq

<Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute>
<CLSCompliant(False)>
Public Class ScriptMain
    Inherits UserComponent

    Public Overrides Sub CreateNewOutputRows()


        Dim strFilePath As String = "C:\MyPath\xmlfile.GetXmlNamespace"
        Dim xml As XDocument = XDocument.Load(strFilePath)


        Output0Buffer.AddRow()

        With Output0Buffer

            .DocumentID = If(xml.Root.Attribute("DocumentID") Is Nothing, "", xml.Root.Attribute("DocumentID").Value.ToString)
            .ExportID = If(xml.Root.Attribute("ExportID") Is Nothing, "", xml.Root.Attribute("ExportID").Value.ToString)
            .JobID = If(xml.Root.Attribute("JobID") Is Nothing, "", xml.Root.Attribute("JobID").Value.ToString)
            .RunID = If(xml.Root.Attribute("RunID") Is Nothing, "", xml.Root.Attribute("RunID").Value.ToString)
            .CreationTime = If(xml.Root.Attribute("CreationTime") Is Nothing, "", xml.Root.Attribute("CreationTime").Value.ToString)
            .StartTime = If(xml.Root.Attribute("StartTime") Is Nothing, "", xml.Root.Attribute("StartTime").Value.ToString)
            .EndTime = If(xml.Root.Attribute("EndTime") Is Nothing, "", xml.Root.Attribute("EndTime").Value.ToString)

        End With

    End Sub

End Class
