The tree does not know where in the xml node to look for the label.
Specifying the labelField tells it this. The "@" indicates the data you
want is in an attribute. So modify your Tree tag like this:
<mx:Tree left="0" top="0" bottom="0" right="0" id="TreeArtes"
dataProvider="{dadosTree.lastResult}"
labelField="@label"/>
If your XML is more complex, or some nodes do not have a "label"(or
whatever) attribute, you can use a labelFunction(). Here is an example:
http://www.cflex.net/showFileDetails.cfm?ObjectID=564
Also, even though what you have is working, I advise against binding
directly to lastResult becaulse it is hard to debug, and you do not have
the opportunity to manipulate the data first. I would declare a
[Bindable] instance variable of type XML, bind the tree to that, then
assign the xml data to that var in your result handler function.

<node label='Bla2'>
<node label='Bla3'>
<node label="Bla4"/>
</node>
</node>
</node>
</Root>
I set the property resultformat as XML and its returning Ok the XML.
the problem is when i use it as a dataprovider. the tree doesen't
shows the right thing, it shows de XMLcode inteasted of the
name(Bla1,BLa2,BLa3 and bla4)
My Mxml is like this:
<mx:HTTPService id="dadosTree" url="criatree.asp" method="POST"
showBusyCursor="true" result="CriaTree();" resultFormat="xml"/>
<mx:Tree left="0" top="0" bottom="0" right="0" id="TreeArtes"
dataProvider="{dadosTree.lastResult}"/>
