Thanks, but, accidentally, Dumper($_) positioned in foreach body shows me variable with CDATA content only, the attribute is lost.
I wish so simple thing, but I am not able to force XML::Simple to put both content and attribute of <httpd> element to some structure, which is an item of array @{$conf->{httpd}} :(
Perhaps I am too tired or too dumb now, but my XML::Trivial is much more simple to use... I publish it after some real experiences, luckilly to avoid headache of some programmers similar to me.
