Sorting a loop by date

Hi,

 

I'm using Simple XML to read from an XML file. I've done a loop for each event. It gives me all the events back in the order of the XML file. However, instead I am trying to sort events by date. Any idea how I could do this?

 

Please see my code below. FYI, the date and time is in UTC timestamp format (eg. 1377361800)

 

Thanks in advance for your help.

 

$newresult = $result->xpath("//match/matchname[.='$uniqueteam']/..");

 

 

  foreach ($newresult as $newmatchlist) {

    

 

 

$newmatch = trim($newmatchlist->{'matchname'}[0]);

$sport = $newmatchlist->{'sportname'}[0];

$tournament = $newmatchlist->{'tournamentname'}[0];

$time=$newmatchlist->{'matchname'}[0]['dateandtime']; 

 

}
