SaveCalDataAsXML

Unit:SDL_geomap
Class: TGeoMap 
Declaration: [1] procedure SaveCalDataAsXML (FileName, DataID: string);
[2] procedure SaveCalDataAsXML (OutStream: TStream; DataID: string);

The method SaveCalDataAsXMLFile stores the contents of the map data as an XML file on the disk (version [1]) or in a stream (version [2]). The parameter FileName specifies the name of the file to be generated, the parameter OutStream specifies the output stream. The parameter DataID holds a unique identifier which is stored as the attribute "id " of the <geomap> tag. For a detailed description of the generated tags please see the method WriteCalDataToOpenXMLFile.

Example: Following is a sample XML code generated by SaveCalDataAsXML. The parameter DataID has been set to 'myDataID': 
<?xml version="1.0"?>
