XML Connector et Dataset

Hi,
Have a quick question, have a xml file like that:
<xml>
<var1></var1>
<var2></var2>
<items>
<item></item>
<item></item>
<item></item>
</items>
</xml>

I’m using the xml connector to retrieve the results then bound the items array to the dataprovider

No problem to access the items but my question is how to access to var1 and var2 in actionscript. Could i bound it to a var?
Thanks for your help.
