The DFM file is the stored form control information in Delphi. Sometimes it is often not too convenient to operate a large number of DFM files (such as quantity replacement controls, checking, etc.). XML is very strong to the structured data reading and writing, and the DFM of the text type is turned to XML, and then the DFM storage is greatly convenient.
