    changing a tree's xml data


      I've been updating my trees xml data by doing this:

      var node:XML = stTree.selectedItem as XML;
      var p:* =node.parent();
      var c:* =node.childIndex();
      var s:* = stTree.selectedIndex;
      var insert:XML = new XML('<i item="some stuff">');
      stTree.dataDescriptor.addChildAt(p, insert, c);
      stTree.dataDescriptor.removeChildAt(p,null,c + 1);

      But it's getting a litle slow to process now my xml is now over 2,000 lines.

      Is there more efficient way than adding/removing a child? I can't see a simple way to edit the attributes of a the xml child element this way.

          You can set the values of the attributes using syntax like this:
          node.@item = "some stuff";

          And you seem to have found another way to delete a node. I've used delete, and collection.removeItemAt(), but never dataDescriptor.removeChildAt()

            i thought i tried the obvious @ attrib and that didn't work, will tryi it again.

            yeah Tracy, but if you delete, edit and/or replace a tree node there seems no other way to maintain the focus on that tree node unless you do it this way. try it yourself mate.

            I just thought that since I have no access to the *computer* through Flex I or noone else could ever be called a Flex 'programmer' . You are script code editor for a JIT bytecode engine. How does that sound?
