Hi -- I am new to XML::Parser.

Question: what the heck does XML::Parser Style=>'Subs' do the function namespace?

It appears the  Subs sets something or other that lets you choose not to define any sub tag {} or  sub tag_{}. That's sort of convenient and cool.

But in the code below, why doesn't perl die on the "subroutine that does not exist" call? It seems Very Dangerous if XML::Parser turns off checking for missing subs. Any way to ask XML::Parser to maintain customary perl behavior -- eg calling a non-existent sub throws a fatal error?

Befuddled --

rkg 

use strict;
use XML::Parser;


my $p1 = new XML::Parser(Style => 'Subs');
$p1->parse('<foo id="me">Hello World</foo>');

sub foo {
    my ($expat, $tag, %a) = @_;
    print "entering foo\n";
    &i_am_a_subroutine_that_does_not_exist();
}

sub foo_ {
    my ($expat, $tag, %a) = @_;
    print "leaving foo\n";
}
