IDtXmlProvider.FormatType

Syntax

FormatType: DtXmlFormatType;

Description

The FormatType property determines file structure format, according to which data is imported. By default format with fields as child nodes is used.

Example

Executing the example requires that the repository contains an ETL task with the ETL identifier and the Data.xml file in the root of the C disk.

XML file structure

Sub UserProc;
Var
    MB: IMetabase;
    MObj: IMetabaseObject;
    EtlTask: IEtlTask;
    EtlProvider: IEtlPlainDataProvider;
    XMLProvider: IDtXMLProvider;
    WxProvider: IWxRectangle;
    WxETLProvider: IWxETLObject;
Begin
    MB := MetabaseClass.Active;
    // Search for ETL task. Repository object with the "ETL" identifier
    MObj := MB.ItemById("ETL").Edit;
    EtlTask := MObj As IEtlTask;
    // Start of data provider creation
    // Create the "Import from XML" object
    EtlProvider := EtlTask.Create(EtlObjectType.PlainDataXMLProvider) As IEtlPlainDataProvider;
    EtlProvider := EtlProvider.Edit;
    EtlProvider.Id := "XML_Provider";
    EtlProvider.Name := "Import from XML";
    EtlProvider.Description := "Import from XML";
    // Set up data provider
    XMLProvider := EtlProvider.Provider As IDtXMLProvider;
    XMLProvider.File := "c:\Data.xml";
    XMLProvider.FormatType := DtXmlFormatType.FieldsAsAttributes;
    XMLProvider.XPath := "Data/Row[@Year > ""1991"" and @Year < ""1993""]";
    XMLProvider.FieldsFromFile;
    EtlProvider.FillDefault;
    // Save data provider
    EtlProvider.Save;
    // End of data provider creation
    // Start of visual object creation
    WxProvider := EtlTask.Workspace.CreateRectangle;
    WxETLProvider := New WxETLObject.Create;
    WxETLProvider.ETLObject := EtlProvider;
    WxProvider.Style.TextPosition := WxTextPosition.Bottom;
    WxProvider.Style.PictureMarginTop := -10;
    WxProvider.PinPosition := New GxPointF.Create(5050);
    WxProvider.Extension := WxETLProvider As IWxShapeExtension;
    // End of visual object creation
    // Save ETL task
    MObj.Save;
End Sub UserProc;

After executing the example the Import from XML object is created in the ETL task. The data provider imports data from the specified XML file. Field values are taken from attribute values of the Row node. Only records with the Year attribute value in the range (1991;1993) are imported.
