Hi:
The PI expression is written in the following manner
(ref. http://www.w3.org/TR/REC-xml )
PI ::= '<?' PITarget (S (Char* - (Char* '?>' Char*)))? '?>'
PITarget ::= Name - (('X' | 'x') ('M' | 'm') ('L' | 'l'))
My query is what does the symbol '-' imply in the above expressions ?
Any pointers in this regard will be appreciated.
Thanks
Tom.
