I'm using simplexml_load_string to load an xml file. Is it possible to order the xml returned by node name.

Example the xml is always returned ordered by <item> but I want to output by <distance>

<item>1</item>
<distance>3</distance>

<item>2</item>
<distance>2</distance>

<item>3</item>
<distance>1</distance>

Any help really appreciated.

You will likely need to assign the nodes to an array (but if memory serves me correctly, they are already in an array) and then use a custom call back function to sort the array.
