Declaration:function ReadFromOpenXMLFile (var InFile : TextFile; DataID: string): boolean;

The function ReadFromOpenXMLFile reads a TRLData structure from the current position of the file InFile. If the parameter DataID is empty, the first <replist> tag is evaluated and read into the data structure. If DataID is not empty, the entire rest of the open file InFile is read until a <replist> 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 ReadFromOpenXMLFile returns TRUE if both a valid starting tag <replist> and a valid end tag </replist> has been found.

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

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

Hint 3: ReadFromOpenXMLFile is by a factor of 5 faster than ReadFromXMLStream. Thus you should use ReadFromOpenXMLFile when reading large data tables with more than approx. 10000 cells.
