Hi -
I understand...
The hash data type is a collection of key/value pairs.
Hash variables are denoted by thr '%' symbol. For example,
my %somehash;
declares an empty hash variable named 'somehash';
To populate a hash, assign values to keys. If the key doesn't
exist the key is created and assigned the value. If the key
is already present, the value is overwritten. Some examples:
$somehash{lunch} = 'hamburger';
assigns the value 'hamburger' to the key 'lunch'; we can
assess that value:
print "$somehash{lunch}\n";
Note hash keys are within curly braces {} and, if they qualify
as a valid perl variable name ([A-X][a-z][0-9]_) they do not need
enclosing quotes. Also note the '%' turns into a '$' when you
access the value.
There is much more to learn about hashes, as well as variables in
general. You should look at:
http://www.perl.org
http://learn.perl.org
as well a some of the links there and take a few of the tutorials
to get up to speed in perl before you tackle your ambitious XML
project.
Aloha => Beau.

Well, of course I dont ask the complete working code ...
English is not my mother language, so maybe my writing was wrong, but I dont
mean that I asked the
complete working code.
Hmm ... I dont understand about 'hash' variable type in perl, could you give
me any 'example' ?
thanks
