Flex tree displaying raw XML with tags

Question

For some reason, after I setup a tree control and set its
dataprovider to an XML that a coldfusion component is returning,
the tree will display the raw XML in one node (including tags and
everything) instead of formatting it into folders and files. At
first I thought the coldfusion component was formatting the XML
incorrectly but after I used one of the example XML's in the adobe
docs, it will still display the RAW xml. This is the code where I
define the tree control:
<mx:Tree x="0" y="10" width="266" height="223"
id="courseTree" dataProvider="{myxml}"/>
and even using this example XML from the livedocs it still
doesnt format it and display folders and entries, it will display
the raw XML with tags:
<mx:XML id="myxml">
<Company label="Macromedia">
<Branch label="Newton">
<Department label="Flex Doc">
<Title label="Intern">
<Name label="Kapil Virdi"></Name>
</Title>
</Department>
</Branch>
</Company>
</mx:XML>

Answer 1

I also tried the following format for the XML as the
datasource, and it still only displays the raw XML and not format
it into folders
<node>
<node label="Finance" dept="200">
<node label="John H" />
<node label="Sam K" />
</node>
<node label="Engineering" dept="300">
<node label="Erin M" />
<node label="Ann B" />
</node>
<node label="Operations" dept="400" isBranch="true" />
</node>
