I have got this XML document. Is there way how to sort the nodes by ascending time and by brand and then count how many cars (samples), true and false was in this time from start time (always the lowest time in the group)?
<?xml version="1.0" encoding="UTF-8"?>
<trade>
<car time="1950" brand="audi" trend="true">
</car>
<car time="1200" brand="renault" trend="true">
</car>
<car time="1000" brand="audi" trend="true">
</car>
<car time="2800" brand="renault" trend="true">
</car>
<car time="2000" brand="audi" trend="true">
</car>
<car time="1500" brand="renault" trend="true">
</car>
<car time="1900" brand="audi" trend="false">
</car>
<car time="2300" brand="audi" trend="false">
</car>
<car time="2100" brand="renault" trend="false">
</car>
</trade>
