does this help
$self->handler( start => "_findreq", 'self,tagname, attr' );

There's some code in report_event() in hparser.c that leads
me to think that it calls methods when "self" is an arg
otherwise it just calls the function, which it appears
by your error message is looking in HTML::Parser
instead of your package
if ((enum argcode)*argspec == ARG_SELF && !SvROK(h->cb)) {
char *method = SvPV(h->cb, my_na);
perl_call_method(method, G_DISCARD | G_VOID);
}
else {
perl_call_sv(h->cb, G_DISCARD | G_VOID);
}
In the Argspec section of the man page
`self'
Self causes the current object to be passed to the
handler. If the handler is a method, this must be the
first element in the argspec.
