Hello,
I've just made a simple script using xml::simple,
and I am stuck on something:
I have an xml file that looks like this:
<person>
<address>
<str>Somewhere</str>
<nr>18</nr>
<sc>a</sc>
</address>
</person>
<person>
<address>
<str>Somewhere else</str>
<nr>3</nr>
<sc>a</sc>
<zone>bc</zone>
</address>
</person>
....
So my question would be, how can I handle dynamic <address> fields
(ex. the above code) and be able to refer to each key/value pair
inside <address> ?
XML::Simple is itself dynamic in that sense. Each address node
becomes a hashref with as many keys as fields it finds. You can then
use each() and friends to inspect them as you'd do with any hash. See
a dump of the structure below.
-- fxn
% cat foo.pl
use XML::Simple;
use Data::Dumper;
my $xml = XMLin(<<EOX);
<test>
<person>
<address>
<str>Somewhere</str>
<nr>18</nr>
<sc>a</sc>
</address>
</person>
<person>
<address>
<str>Somewhere else</str>
<nr>3</nr>
<sc>a</sc>
<zone>bc</zone>
</address>
</person>
</test>
EOX
print Dumper($xml);
% perl foo.pl
$VAR1 = {
'person' => [
{
'address' => {
'sc' => 'a',
'str' => 'Somewhere',
'nr' => '18'
}
},
{
'address' => {
'sc' => 'a',
'str' => 'Somewhere else',
'zone' => 'bc',
'nr' => '3'
}
}
]
};
