Question

I am trying to insert child node in xml via actionscript as follow –

var xml:XML = <menu>
<item>burger</item>
<item>soda</item>       
</menu>;
xml.insertChildAfter(xml.item[0], <item>fries</item>);
trace(xml);
----------output---------------
<menu>
  <item>burger</item>
  <item>fries</item>
  <item>soda</item>
</menu>
-------------------------

the above code is working fine as expected, but when i am trying to insert a child in nested child, i am unable to insert.

but below is not working-

var xml:XML = <menu>
<my>
<item>burger</item>
<item>soda</item>
</my>
</menu>;
xml.insertChildAfter(xml.my.item[0], <item>fries</item>);
trace(xml);
------------output-------------
<menu>
  <my>
    <item>burger</item>
    <item>soda</item>
  </my>
</menu>

---

moreover it returns undefined and as described in actionscript livedocs –

If you call this method on an XML child that is not an element (text, attributes, comments, pi, and so on) undefined is returned.

any help/input is greatly appreciated, thanks for stopping by.

Answer 1

The first parameter of insertChildAfter must be a direct child of the XML node you are calling the method on. So try:

var xml:XML = <menu>
<my>
<item>burger</item>
<item>soda</item>
</my>
</menu>;
xml.my.insertChildAfter(xml.my.item[0], <item>fries</item>);
trace(xml.toXMLString());
