Seems like this will do the trick.. But be sure to check the caveats (e.g. ordering) in the
XML::Simple for when not to use that module. Also, I came up with the code below by first making the DATA contain
<httpd foo="bar"> and Data::Dumper'ing $conf to see what XML::Simple's data structure was.
use strict;
use warnings;
use XML::Simple;
my $xs = XML::Simple->new(ForceArray=>['httpd']);
my $s = do { local $/=undef; <DATA> };
my $conf = $xs->XMLin($s);
my $ct = 0;
foreach my $httpd ( @{$conf->{httpd}} ){
$ct++;
if( ref($httpd) eq 'HASH' ){
$httpd->{number} = $ct;
}else{
$httpd = { content=>$httpd, number=>$ct };
}
}
my $xml = $xs->XMLout($conf);
print $xml;
__DATA__
<x>
<httpd><![CDATA[
...1st piece of httpd configuration
]]></httpd>
<httpd><![CDATA[
...2nd piece of httpd configuration
]]></httpd>
</x>
