Grep a YAML file in Perl

Question

Are there any modules in Perl which can grep an arbitrary hierarchy in a yaml file - just like ygrep in python? Or code which can do that? I tried googling but didn't find any resources/pointers for it. I have been trying since a few hours without much luck.

LoadFile 返回哈希引用.

my $href = YAML::LoadFile("file.yaml");

检查CPAN是否有任何深度数据结构遍历模块,例如
