perl编译错误

Question

以下代码出错：

 if (! defined $dchash{$location}) {
    die "Unrecognized realm: $location";
    }
 elsif ($dchash{$location}) ne $realm) {
    die "Incorrect realm for host in $location, expected $dchash{$location} got $realm";
    }

syntax error at ./test.pl line 73, near ") ne"
Execution of ./test.pl aborted due to compilation errors.

验证$ realm的正确语法是什么？？

Answer 1

)行上的第一个elsif字符导致问题。删除它应该消除语法错误。
