select specific data in a xml file

I've got this xml file

<data-set xmlns:xsi="http://ift.tt/ra1lAU">
    <record>
        <Date>1 July</Date>
        <Ville>New-York</Ville>
        <haute>6h50</haute>
        <basse>1h14</basse>
        <haute2>20h01</haute2>
        <basse2>13h16</basse2>
    </record>
    <record>
        <Date>2 July</Date>
        <Ville>New-York</Ville>
        <haute>7h36</haute>
        <basse>1h59</basse>
        <haute2>20h41</haute2>
        <basse2>13h56</basse2>
    </record>
    <record>
        <Date>3 July</Date>
        <Ville>Miami</Ville>
        <haute>8h21</haute>
        <basse>2h44</basse>
        <haute2>21h22</haute2>
        <basse2>14h37</basse2>
    </record>
</data-set>

I would like, in my AS3 code, to be able to select specific data from this xml file.

Example :

var currentDate=new Date();
var day=currentDate.getDate();

If the day == one of the day of the xml, display "haute" of the corresponding day.

Is it possible ? How can I do that ?
