If you just want the CDATA portion, there is really no point to use DOM. Instead, use XML::Parser or XML::Parser::Expat, and do something like this:
use XML::Parser::Expat;
use strict;
my $xml_string;
open(FOO, "test.xml") or die "failed to open";
local $/ = undef;
$xml_string = <FOO>;
close(FOO);
my $parser = new XML::Parser::Expat;
my $first;
$parser->setHandlers(CdataStart => \&start,
CdataEnd => \&end
);
$parser->parse($xml_string);
sub start {
$first = $_[0]->current_byte;
}
sub end {
print substr($xml_string, $first, $_[0]->current_byte - $first + 1
+);
}
