我正在尝试找到从智能手机解析传感器数据的最快方法,以用于实时应用程序.格式如下所示:
<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<NodeId>0</NodeId>
<Accelerometer>
<Accelerometer1>-.1875240802764893</Accelerometer1>
<Accelerometer2>4.6734819412231445</Accelerometer2>
<Accelerometer3>8.312667846679688</Accelerometer3>
</Accelerometer>

<Gyroscope1>-0.10551923513412476</Gyroscope1>
<Gyroscope2>0.009592439979314804</Gyroscope2>
<Gyroscope3>0.019185146316885948</Gyroscope3>
</Gyroscope>
<Gravity>
<Gravity1>-1.2976515293121338</Gravity1>
<Gravity2>3.672762393951416</Gravity2>
<Gravity3>9.003327369689941</Gravity3>

可用的传感器数据可能会因手机而异.但是一旦建立连接,包的结构就不会改变,因此可能会跳过部分解析.
最佳答案 如果解析速度是您的关键因素,请考虑使用
cElementTree或
lxml.
肯定有更多的选择,请看这些主题:
