I got it working now I used ns = { 'nms' : 'http://networks.com/nms <http://networks.com/nms%7Dtemplate-name').text>' } And then l.find('nms:template-name', ns) I also want to extract the namespace and I see this gets me the namespace str(root[0]).split('{')[1].split('}')[0] Is there a better way to extract the name space? > > > > 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.
