Hi Tim,
A good suggestion. Unfortunately my collection is not sorted, and a
sort would cause some issues with the display of the Tree that uses my
collection as a dataProvider.
Bryan,
Your code example is good, but I feel that it will only work for 2
levels of nodes.
My XML structure has no limit to the number of levels of nodes. Thus
its an n-level tree.
I have however attempted the following approach with success! Please
feel free to use this code sample:
=============================================================
===== XML Example
=============================================================
<element id="hello">
<element id="world">
<element id="123"/>
<element id="graham"/>
<element id="weldon">
<element id="office">
<element id="thing"/>
<element id="boat"/>
<element id="chair"/>
</element>
<element id="person"/>
</element>
</element>
</element>
=============================================================
=============================================================
===== FUNCTION: insertItem(_parentId, _child)
=============================================================
public function insertItem(_parentId
: String, _child : XMLList) : Boolean
{
var parentElement : XMLList =
this.findItem(_parentId);
// ---- Exit if we didnt find the parent
if (parentElement == null)
return false;
// ---- Add the child element to the
parent's children collection
parentElement.* += _child;
return true;
}
=============================================================
=============================================================
===== FUNCTION: findItem(_id, _xml)
=============================================================
public function
findItem (_id : String, _xml : XMLList) : XMLList
{
// ---- Check if the supplied element is
the one we're looking for
if ([EMAIL PROTECTED] == _id)
return _xml;
var children : XMLList =
_xml.element;
var result : XMLList = null;
for each (var x : XML in children)
{
// ---- Recurse, looking at children.
result = this.findItem(_id,
new XMLList(x));
// ---- Return the result if its not
null, ending the recursion
if (result != null)
return result;
}
return null;
}
=============================================================

Graham Weldon

Hi Graham,
I'm not sure if it works, but have you tried this approach?
var myTreeData:ICollectionView = new XMLListCollection();
var myCursor:IViewCursor = myArrayCollection.createCursor();
myCursor.findFirst([EMAIL PROTECTED]:"9998"});
// maybe just Id?. According to the docs, this only works if the
collection is sorted.
myCursor.insert({label:"thing", id:"9999"});
// might be different syntax for XML
