TableAttributeValue: String;
The TableAttributeValue property determines the value of the table attribute, data of which has to be imported.
Is used together with the TableAttributeName property. It is relevant if the TableIdentificationType property is set to the DtWebTableIdentificationType.ByAttribute value.
Executing the example requires that the repository contains an ETL task with the Etl identifier and the HTML file Data.html in the disk C root directory. There is an attribute NameTable in the table code in the <Table> tag.
Sub Main;
Var
MB: IMetabase;
MObj: IMetabaseObject;
EtlTask: IEtlTask;
EtlProvider: IEtlPlainDataProvider;
WebProvider: IDtWebProvider;
WxProvider: IWxRectangle;
WxETLProvider: IWxETLObject;
Begin
MB := MetabaseClass.Active;
//ETL task search. Repository object with the ETL identifier
MObj := MB.ItemById("Etl").Edit;
EtlTask := MObj As IEtlTask;
//Start of the provider creation
//The Import From Web object creation
EtlProvider := EtlTask.Create(EtlObjectType.PlainDataWebProvider) As IEtlPlainDataProvider;
EtlProvider := EtlProvider.Edit;
EtlProvider.Id := "Web_Provider";
EtlProvider.Name := "Import from Web";
EtlProvider.Description := "Import from Web";
//Set up data provider
WebProvider := EtlProvider.Provider As IDtWebProvider;
WebProvider.HasHeader := True;
WebProvider.TableIdentificationType := DtWebTableIdentificationType.ByAttribute;
WebProvider.TableAttributeName := "NameTable";
WebProvider.TableAttributeValue := "Two_Table";
WebProvider.Url := "c:\Data.html";
EtlProvider.FillDefault;
//Save provider
EtlProvider.Save;
//End of 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(50, 50);
WxProvider.Extension := WxETLProvider As IWxShapeExtension;
//End of visual object creation
//Save Etl task
MObj.Save;
End Sub Main;
After executing the example the Import from Web object is created in the ETL task. The provider imports data from the Data.html HTML file. Importing table is searched by attribute NameTable values. Field names are imported from the first table row.
