Only one root tag is allowed.

Question

I'm trying to run the following (from Flex 2.0 Online help) :
<?xml version="1.0"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:XML id="capitals" format="e4x">
<Capitals label="U.S. State Capitals">
<capital label="AL" value="Montgomery" />
<capital label="AK" value="Juneau"/>
<capital label="AR" value="Little Rock"/>
<capital label="AZ" value="Phoenix"/>
</Capitals>
<Capitals label="Canadian Province Capitals">
<capital label="AB" value="Edmonton" />
<capital label="BC" value="Victoria"/>
<capital label="MB" value="Winnipeg"/>
<capital label="NB" value="Fredericton"/>
</Capitals>
</mx:XML>
<!-- Create an XMLListCollection representing the Tree
nodes.
capitals.Capitals is an XMLList with both Capitals elements.
-->
<mx:XMLListCollection id="capitalColl"
source="{capitals.Capitals}" />
<!-- When you use an XML-based data provider with a tree
you must specify
the label field, even if it is "label".
The XML object includes the root, so you must set
showRoot="false".
Remember that the Tree will not, by default, reflect dynamic
changes
to the XML object. -->
<mx:Tree id="Tree1" dataProvider="{capitals}"
labelField="@label"
showRoot="false" width="300" />
<!-- The XMLListCollection does not include the XML root.
-->
<mx:Tree id="Tree2" dataProvider="{capitalColl}"
labelField="@label"
width="300" />
</mx:Application>
and I get
Only one root tag is allowed.
Any idea what has to change?
Thanks

Like it says, that is invalid xml. It looks like it is a bug
in the example doc.
Add a root node to the xml and you should be ok.
