$key2value is a hash reference, you retrieve the value for a this way: $key2value->{a}

see perldata for more info.

I had tried that at first and it does print the value, but it also prints: Use of uninitialized value $key2value{"a"} in concatenation (.) or string for each "settings" element in the xml.	[reply]

`$key2value{"a"}` and `$key2value->{"a"}` are two different and absolutely unrelated things. The first attempts to get the value of the key "a" in hash `%key2value`, the other in the hash referenced by the scalar variable `$key2value`. Two different variables, no surprise that you do not find anything in one after you wrote to the other. Jenda Enoch was right! Enjoy the last years of Rome.	[reply] [d/l] [select]
