ISearchEngineServiceBase.LoadFromXml

Fore Syntax

LoadFromXml(Reader: Variant);

Fore.NET Syntax

LoadFromXml(Reader: Object);

Parameters

Reader. The XML element from which search service parameters are loaded.

Description

The LoadFromXml method loads parameters of the search service from specified XML element.

Comments

As the Reader parameter it is necessary to determine an XML element described by the IXmlDomElement interface. The structure of child elements must be generated using the SaveToXml method.

Fore Example

Executing the example requires a file named SearchEngine.xml in the root directory of the disc C. Parameters of search service should be saved in the file. Connect the BISearch, Metabase, XML system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    SearchFactory: ISearchEngineServiceFactory;
    SearchEngine: ISearchEngineServiceBase;
    XMLDoc: IXMLDOMDocument3;
Begin
    MB := MetabaseClass.Active;
    SearchFactory := New SearchEngineServiceFactory.Create;
    SearchEngine := SearchFactory.CreateSearchEngine(MB);
    //Load settings from the XML file
    XMLDoc := New DOMDocument60.Create;
    XMLDoc.load("c:\SearchEngine.xml");
    SearchEngine.LoadFromXml(XMLDoc.documentElement);
    //...
    //Work with search platform
    //...
End Sub UserProc;

On executing the example an object that gives access to the search service is created. Object settings will be loaded from selected file.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

Imports Prognoz.Platform.Interop.BISearch;
Imports Prognoz.Platform.Interop.Metabase;
Imports Prognoz.Platform.Interop.MsXml2;

Public Shared Sub Main(Params: StartParams);
Var
    MB: IMetabase;
    SearchFactory: SearchEngineServiceFactory = New SearchEngineServiceFactoryClass();
    SearchEngine: ISearchEngineServiceBase;
    XMLDoc: IXMLDOMDocument3;
Begin
    MB := Params.Metabase;
    SearchEngine := SearchFactory.CreateSearchEngine(MB);
    //Load settings from the XML file
    XMLDoc := New DOMDocument60();
    XMLDoc.load("c:\SearchEngine.xml");
    SearchEngine.LoadFromXml(XMLDoc.documentElement);
    //...
    //Work with search platform
    //...
End Sub;
