I have a simple example
var myXML:XML =
<root>
<element type="a">I am a</element>
<element type="b">I am b</element>
</root>
;
I cant work out how I can programatically remove an element of a specific type
delete myXML.root.element.type['a'][0];
To remove a XML element by matching an attribute of that element, I believe you're looking for:
var index:int = myXML.element.(@type=="b").childIndex();
delete myXML.element[index];
Based upon your XML:
var myXML:XML =
<root>
<element type="a">I am a</element>
<element type="b">I am b</element>
</root>;
After calling this function, the XML would be:
<root>
<element type="a">I am a</element>
</root>
