Hello,
I built a hash as follows:
# build hash
while() {
...
$hshFoo{$key1}{$key2} = $strFileName;
...
# key1 is a number
# key2 is a sequential number
}
When I attempt to reference the hash I get the following:
foreach $key (keys %hshFoo) {
print " $key => $hshFoo{$key}\n";
}
Output:
6137 => HASH(0x1ddba60)
2823 => HASH(0x1ddbd18)
6598 => HASH(0x1ddbc88)
4156 => HASH(0x1ddbd00)
Whereas "HASH(0x1ddba60)" contains:
6137 =>
0 => file1.xml
1 => file2.xml
2 => file3.xml
What is the best way to reference the 2nd hash?
I tried to create a temp hash of $hshFoo{$key}
to loop through, but that failed. I need to be
able to reference the 2nd key+value pair; in
this case of the hash "HASH(0x1ddba60)".
I tried this also...
foreach $key2 (keys $hshFoo{$key}) {
...
}
Type of arg 1 to keys must be hash (not hash element) at foo.pl line
341, near "}) "
BEGIN not safe after errors--compilation aborted at foo.pl line 431.
