From one string to two, with filter between string
<p>I have this string:</p>

<pre><code>[{"position":"1d","number":10,"nb_plot1":12,"max_actions":3}
{"position":"2d","number":7,"nb_plot1":15,"max_actions":30}
{"position":"3d","number":100,"nb_plot1":2,"max_actions":5}]
</code></pre>

<p>and i need to obtain two different string with different format like this:</p>

<p>for numbers:</p>

<pre><code>[10,7,100]
</code></pre>

<p>for positions:</p>

<pre><code>['1d','2d','3d']
</code></pre>

<p>and cut unnecesarry strings.</p>

<p>I'm a noob sorry.</p>
