This is the xml file. The code which is reading it is given below.

$simple1 = XML::Simple->new(ForceArray=>1, KeepRoot=>1);
$data1   = $simple->XMLin("query.xml");
print Dumper($data1) . "\n";

Now, I want to read the key elements (topN, layer, filter, name, datatype) values in different variables. But I did not find a any code which will read the above data structure and extract those values, looping through throught the number of queries. For example - code in this case should loop 2 times as you can see that there are two queries in the xml file (query.xml). Please help!
