How to read the XML files

[snippsat]

I am new to Python, i tired using different modules available in the python
but unable to read this xml file.

Then you should post code and what you tried.
Both BeautifulSoup and lxml is fine for this.

from bs4 import BeautifulSoup

xml = '''\
<?xml version="1.0"?>
<OMeS version="2.3">
	<PMSetup startTime="2018-06-03T00:15:00.000-05:00:00" interval="15">
		<PMMOResult>
			<MO dimension="network_element">
				<DN>NTHLRFE-1/DDH-1/AFW-1</DN>
			</MO>
			<PMTarget measurementType="AFW">
				<AFW_TC_L_CANCEL>0</AFW_TC_L_CANCEL>
				<AFW_TC_L_REJECT>0</AFW_TC_L_REJECT>
				<AFW_TC_NOTICE>0</AFW_TC_NOTICE>
				<AFW_TC_R_REJECT>0</AFW_TC_R_REJECT>
				<AFW_TC_U_REJECT_IN>0</AFW_TC_U_REJECT_IN>
				<AFW_TC_U_REJECT_OUT>0</AFW_TC_U_REJECT_OUT>
				<SENT_TCABRT_POLICING>0</SENT_TCABRT_POLICING>
				<SNT_VIRGT_MULPLM>0</SNT_VIRGT_MULPLM>
			</PMTarget>
		</PMMOResult>
	</PMSetup>
	<PMSetup startTime="2018-06-03T00:15:00.000-05:00:00" interval="15">
		<PMMOResult>
			<MO dimension="network_element">
				<DN>NTHLRFE-1/BRM-hlrda001/CPU-12</DN>
			</MO>
			<PMTarget measurementType="CPU">
				<cpuLoad>1.93</cpuLoad>
				<cpuUsed>106</cpuUsed>
			</PMTarget>
		</PMMOResult>'''

soup = BeautifulSoup(xml, 'xml')

Test:

>>> pm = soup.find('PMTarget', {'measurementType': "AFW"})
>>> pm
<PMTarget measurementType="AFW">
<AFW_TC_L_CANCEL>0</AFW_TC_L_CANCEL>
<AFW_TC_L_REJECT>0</AFW_TC_L_REJECT>
<AFW_TC_NOTICE>0</AFW_TC_NOTICE>
<AFW_TC_R_REJECT>0</AFW_TC_R_REJECT>
<AFW_TC_U_REJECT_IN>0</AFW_TC_U_REJECT_IN>
<AFW_TC_U_REJECT_OUT>0</AFW_TC_U_REJECT_OUT>
<SENT_TCABRT_POLICING>0</SENT_TCABRT_POLICING>
<SNT_VIRGT_MULPLM>0</SNT_VIRGT_MULPLM>
</PMTarget>

>>> pm.find('AFW_TC_NOTICE')
<AFW_TC_NOTICE>0</AFW_TC_NOTICE>

>>> pm.find('AFW_TC_NOTICE').text
'0'
>>>
