xml_SetPIHandler ( parserID; handler )
- --> parserID : longint
- --> handler : string[31]
PI in this case is not the mathematical constant, but an abbreviation for processing instruction. This command sents the handler method for processing instructions. The handler method is passed the parserID, processing instruction target, and the data.
