create an array from elements in a string, elemets start with certain key/sign : <p>I want to abstract an array with text strings that reside in a text, each text element starts with a certain sign or key e.g. $ or &amp;. how can I achieve this?</p>

<p>so "$Huey, $Dewey, and $Louie all live in Duckcity. $Goofy and $Mickey live there too." should result in </p>

<pre><code>string characters = {"Heuy","Dewey", "Louie", "Goofy","Mickey"};
</code></pre>
