A PATH is allowed to belong to a very restricted subset of // Goessner's JSONPath. // So, // var s = '[{"$ref":"$"}]'; // return JSON.retrocycle(JSON.parse(s)); // produces an array containing a single element which is the array itself. var px = /^\$(?:\[(?:\d?|\"(?:[^\\\"\u0000-\u001f]|\\([\\\"\/bfnrt]|u[0-9a-zA-Z]{4}))*\")\])*$/; </code></pre> <p>In the px regular expression, only one digit array indexes are allowed, not two.<br> Since the path does not match the pattern, it will not replace the reference.</p> <p>You could try using a local copy of cycle.js and changing the px regular expression to:</p> <pre><code>var px = /^\$(?:\[(?:\d+|\"(?:[^\\\"\u0000-\u001f]|\\([\\\"\/bfnrt]|u[0-9a-zA-Z]{4}))*\")\])*$/; </code></pre> <p>Note the difference from the previous regular expression: we are saying that we will now allow one or more digits in array indices. This is accomplished by replacing the single ? character after the first d with a +.</p> <p><strong>Edit:</strong> Newer versions of the <a href="https://github.com/douglascrockford/JSON-js/commits/master/cycle.js" rel="nofollow">cycle.js</a> retrocycle function now allow array indices that are greater than 9.</p>
