search hash keys

[al0]

Hi,

I have made a data structure that consists of hash and the keys referencing to arrays. The key names comes from the first elements in the array it referencing to. The thing I trying to accomplish is to be able to search trough all keys and print all that matches the string. From the keys that get listed from the search in the program I want to be able to get more detail about the key, by going into to that key's array.

I guess regular expressions would work for this but I dont know exactly where to begin.

You can get the matching keys like so:

my @matching_keys = grep $_ eq "what you're looking for", keys %hash;

This works only if you type the exact keyname. I want to be able to search for example "test" and get all keys that consist of the word "test".

 

[ishnid]

The "exact keyname" and "keys that consist of the word 'test'" are the same thing, no?

Perhaps you mean keys that *contain* the word test?

 

[al0]

Yes I mean contain, pardon my english. So if I have these keys for example:

sometest
some test
testing
other keys

If I search for "test" I want to get the first three keys.

to borrow from ishnids code:

my @matching_keys = grep {/test/} keys %hash;
