IDtWebProvider.TableIdentificationType

Syntax

TableIdentificationType: DtWebTableIdentificationType;

Description

The TableIdentificationType property determines table identification type on the Web page.

Example

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 source 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";

//Data source setting

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;

//Saving the source

EtlProvider.Save;

//End of source 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 source 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.
