<attribute id="119" type="Option" name="Listing Type">Used</attribute>
<attribute id="36" type="Integer" name="Year">2007</attribute>
<attribute id="35" type="Price" name="Price" currency="NZD" gst="15" gst_value="ex-GST">18900</attribute>
<attribute id="19" type="Paragraph" name="Description">New Holland BR750 done 35000 bales, tidy baler, crop cutter, hyd reverser, brakes, runs very well.</attribute>
<listing id="298499">
<model>B/D Combination</model>
<attribute name="Item Condition" id="236" type="Option">New</attribute>
<attribute name="Year" id="36" type="Integer">2007</attribute>

<attribute name="Price" id="35" type="Price" currency="AUD" gst="10" gst_value="ex-GST" price_type="Drive Away no more to Pay">202141.82</attribute>

How can I sort the 2 listings by Year or Price in php? Cheers.

What method are you using to read your XML?
Are you actually wanting to rewrite your XML in the sorted order?
Or is this only for display?
What have you tried so far?
