NAME
XML::Genx::Constants - constants for genx
SYNOPSIS
use XML::Genx::Constants qw( GENX_SEQUENCE_ERROR );
my $w = XML::Genx->new;
eval { $w->EndDocument };
die "programmer error"
if $@ == GENX_SEQUENCE_ERROR;
DESCRIPTION
This module provides constants for use with XML::Genx. They are mostly used for checking the value of an exception that's been thrown. Exceptions that XML::Genx throws are set up as "dual valued scalars". This means that they contain both a string and a number in the same part. So if you compare them to one of the constants exported by this module, they do the right thing. This is similiar to the $! variable.
