Class:TMatrix, TIntMatrix, TMat3D
Declaration:function LoadFromXMLFile (FName: string; DataID: string): boolean;

The function LoadFromXMLFile reads a matrix from the file FName. If the parameter DataID is empty, the first <matrix> tag is evaluated and read into memory. If DataID is not empty, the entire file is read until a <matrix> tag is found whose attribute "id " matches DataID (the recognition of the "id " attribute is not case-sensitive). The property DataID is set to the identification string of the XML data source. The function LoadFromXMLFile returns TRUE if both a valid starting tag <matrix> and a valid end tag </matrix> has been found and the matrix has been updated. In this case the OnChange event is triggered.

Hint 1: For a description of the valid tags, please see WriteToOpenXMLFile.

Hint 2: The XML description of the matrix data has to follow a certain order: number of columns and rows have to precede all other data.
