我只对这个数据中的'accelx'和'accely'值感兴趣,并且需要从中创建一个csv。
更新:当我使用以下内容更改第二行时,下面给出的代码会中断。因此没有显示任何内容;
<ArrayOfRecord xmlns:i="http://www.w3.org/2001/XMLSchema-instance" i:type="Record" xmlns="http://schemas">
以下代码有效:
import xml.etree.ElementTree as etree
tree = etree.parse(r"C:\Users\data.xml")
root = tree.getroot()
val_of_interest = root.findall("./Values/SensorValue")
for sensor_val in val_of_interest:
print sensor_val.find('accelx').text
print sensor_val.find('accely').text
