( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I can convert my data from JSON to objects using the Perl JSON module (http://search.cpan.org/dist/JSON/), but I am having difficulty accessing the data in perl objects. The data appears to be in an array of hashes, but I cannot use any object accessor functions to get at the data. Here's a sample of the data:
{ "items" : [ { "name" : "Theodor Nelson", "id": "_333301" }, { "name": "Morton Heilig", "id": "_13204" } ] }
Here's a snippet of my code. Note $inventors_obj holds the data.
$inventors_obj = jsonToObj($inventors_json[0]); #I want to iterate through my list of inventors @inventors_array = $inventors_obj->{"items"};
But $inventors_obj->{"items} appears to be returning a single object, rather than an array. How can iterate through it, change things, and print it back to JSON?
#print name doesn't work, because the entire object is #stored at $inv +entors_array[0]. print $inventors_array[0]->{"name"} #So this doesn't work: print $inventors_array[1]->{"name"} #I am not sure if this is possible to even alter data #generically wit +h objects, even though I thought they were #really just arrays of hashes: $inventors_array[1]->{"name"} = "New Name"; #But I can do with an array of hashes... $inventors_array[1]{"name"} = "New Name";
However, if I convert the object to an array of hashes (how do I do this, "unblessing"?), can I get it back out in JSON? Is there a way I can manipulate it while keeping it as an object?

  • 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).
