This is what I tried for l in root.findall('{http://networks.com/nms}template-metadata'): print l.find('template-name').text I am following the doc https://docs.python.org/2/library/xml.etree.elementtree.html section 19.7.1.3 findall example I get this error attribute error 'NoneType' object has no attribute text. I do not understand why l.find('template-name') is NoneType. Here is complete code with output. import xml.etree.ElementTree as ET xmlfile=''' <collection xmlns:y="http://tail-f.com/ns/rest";> <template-metadata xmlns="http://networks.com/nms";> <template-name>ALLFLEX-BLOOMINGTON</template-name> <type>post-staging</type> <device-type>full-mesh</device-type> <provider-tenant>ALLFLEX</provider-tenant> <subscription xmlns="http://networks.com/nms";> <solution-tier>advanced-plus</solution-tier> <bandwidth>1000</bandwidth> <is-analytics-enabled>true</is-analytics-enabled> <is-primary>true</is-primary> </subscription></template-metadata></collection>''' root = ET.fromstring(xmlfile) print root.tag print root[0][0].text for l in root.findall('{http://networks.com/nms}template-metadata'): print l.find('template-name').text collection ALLFLEX-BLOOMINGTON ---------------------------------------------------------------------------AttributeError Traceback (most recent call last)<ipython-input-18-73bd6770766a> in <module>() 19 print root[0][0].text 20 for l in root.findall('{http://networks.com/nms}template-metadata'):---> 21 print l.find('template-name').text AttributeError: 'NoneType' object has no attribute 'text' ... > > > _______________________________________________ > Tutor maillist - Tutor@python.org > To unsubscribe or change subscription options: > https://mail.python.org/mailman/listinfo/tutor > -- Asif Iqbal PGP Key: 0xE62693C5 KeyServer: pgp.mit.edu A: Because it messes up the order in which people normally read text.
