( #3333=superdoc: print w/replies, xml ) Need Help??

Building on AppleFritter's answers:

You can combine the loop through your results with the hash-building using map, which transforms one list into another, while performing some action on each element. In this case the action would be to add the appropriate key and value to your hash. (And we can transform the first list into a hash because a hash is a list of pairs ...)

my %json_hash = however_you_got_it(); my %new_hash = map { $_->{'certname'} => $_ } values %{ $json_hash{'r +esults'} };
Here map takes each element of the list returned by values(), which is a hashref, extracts the value of its key 'certname', uses that as the key in the new hash, and uses the entire hashref as the value.

Also note that I dereferenced the hashref $json_hash{'results'} before using it, because it's not "stable" Perl code to call values() (or keys()) on a hashref. I imagine you got a warning like "values on reference is experimental at ...", no?

Hope this helps!


The way forward always starts with a minimal test.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
