If none of the subs that this style looks for is there, then the effect of parsing with this style is to print a canonical copy of the document without comments or declarations. All the subs receive as their 1st parameter the Expat instance for the document they\*(Aqre parsing. .PP It looks for the following routines: .IP \(bu 4 StartDocument .Sp Called at the start of the parse . .IP \(bu 4 StartTag .Sp Called for every start tag with a second parameter of the element type. The \f(CW$_\fR variable will contain a copy of the tag and the \f(CW%_\fR variable will contain attribute values supplied for that element. .IP \(bu 4 EndTag .Sp Called for every end tag with a second parameter of the element type. The \f(CW$_\fR variable will contain a copy of the end tag. .IP \(bu 4 Text .Sp Called just before start or end tags with accumulated non\-markup text in the \f(CW$_\fR variable. .IP \(bu 4 PI .Sp Called for processing instructions. The \f(CW$_\fR variable will contain a copy of the PI and the target and data are sent as 2nd and 3rd parameters respectively. .IP \(bu 4 EndDocument .Sp Called at conclusion of the parse.
