in thread Does this ctor make sense?

Yes, and it’s a core module, so if you have Perl, you already have Data::Dumper:

#! perl use strict; use warnings; use Data::Dumper; my %families = ( Flintstone => { husband => 'Fred', wife => 'Wilma', daughter => 'Pebbles', }, Rubble => { husband => 'Barney', wife => 'Betty', son => 'Bamm-Bamm', }, ); print Dumper(\%families), "\n";

To get similar output with print alone, you would need to write your own loops.

I didn't know Data::Dumper

Seriously, get to know it as soon as possible, it’ll save you a lot of time. Or you might prefer one of the alternatives on CPAN, such as Data::Dump.

Hope that helps,

[ambrus]: The main loop for unixish systems is in https://metacpan. org/source/ KARASIK/Prima-1. 49/unix/apc_app.c. It is a hand-rolled select loop, but also always spins at least once every 0.2 seconds for some reason.
[ambrus]: marto: no, not that way. if you just want to test for an existing id attribute, then write *[@id] , or you can match a regexp to the value of that attribute like *[@id=~/something/ ]
[marto]: ambrus, thanks I ended up going with '//*[starts- with(@id, "thread_")]...
[ambrus]: Sometimes it's easier to just match elements in ways other than xpath, like directly with perl code.
