Delete XML nodes in Flex

This is about deleting a node from XML in Flex. Here our XML is assigned to a variable, treeXml.

var treeXml: XML = <root>
                       <node label="abc">
                             <node label="Page"></node>
                             <node label="Business"></node>
                             <node label="Application"></node>
                             <node label="Loyalty"></node>
                        </node>
                        <node label="def">
                             <node label="Page"></node>
                             <node label="Business"></node>
                             <node label="Application"></node>
                             <node label="Loyalty"></node>
                        </node> 
                     </root>

Suppose we need to delete the node with label 'abc'. The way to do it is;

delete treeXml.node.(@label=="abc")[0];

Above code deletes the child (node) which is having the attribute label equal to 'abc'. Notice '[0]' at the end of the statement. After this, treeXml would be;

                    <root>
                         <node label="def">
                              <node label="Page"></node>
                              <node label="Business"></node>
                              <node label="Application"></node>
                              <node label="Loyalty"></node>
                         </node> 
                    </root>
