title: AS3 Delete child node from XML by child value
body: <p>I've got an XML with a structure like the following;</p>
  
  <pre><code> &lt;items&gt;
      &lt;item&gt;5&lt;/item&gt;
      &lt;item&gt;3006&lt;/item&gt;
      &lt;item&gt;25&lt;/item&gt;
      &lt;item&gt;458&lt;/item&gt;
      &lt;item&gt;15&lt;/item&gt;
      &lt;item&gt;78&lt;/item&gt;
   &lt;/items&gt;
  </code></pre>
  
  <p>How do I delete the item with the value 458. Just to clarify this, I don't know the index of that item, so simply calling delete items[index] won't do here.
  I have to delete by value. </p>
  
  <p>Any hints?</p>
