у меня 8000 строк, похожих на это
<Flow flowId="1" timeFirstTxPacket="+0.0ns" timeFirstRxPacket="+924100.0ns" timeLastTxPacket="+199984927558.0ns" timeLastRxPacket="+199675473275.0ns" delaySum="+2287566662167.0ns" jitterSum="+65280162191.0ns" lastDelay="+3511349483.0ns" txBytes="161956" rxBytes="116536" txPackets="3125" rxPackets="2251" lostPackets="640" timesForwarded="0">
и что мне нужно сделать, это суммирование rxPackets в каждой строке вместе и txPackets тоже
я имею в виду общую сумму в 8000 строк
заранее спасибо
