Python3如何搜索子节点xml.etree.ElementTree对于lis中的字符串

Question

我想让这更简单，并能够搜索变量列表：报警1，报警2，报警3。。。在报警dict.values（）

到目前为止我所掌握的有效方法：

import xml.etree.ElementTree as ET 
tree = ET.parse (path.filename) #XML file 
root = tree.getroot()


for child in root:
    alarmDict = child.attrib      #This lists the alarm codes as dicts  
    if 'alarm1' in alarmDict.values(): print ('Contains this alarm', 'alarm1')
    if 'alarm2' in alarmDict.values(): print ('Contains this alarm', 'alarm2')
    if 'alarm3' in alarmDict.values(): print ('Contains this alarm', 'alarm3')

我要做的是：

^{pr2}$

Answer 1

你需要另一个循环：

for child in root:
    alarmDict = child.attrib      #This lists the alarm codes as dicts
    alarm_list = [alarm1, alarm2, alarm3]  
    for alarm in alarm_list:
        if alarm in alarmDict.values():
            print('Contains this alarm', alarm)
