how can parse out '2.16' 'bc_10year'? i've been looking @ other examples elementtree , lxml , can't seem match xml format in examples of file.

the last thing i've tried was:

from lxml import etree doc = etree.parse(yield_xml) memoryelem = doc.find('content') print memoryelem.text        # element text print memoryelem.get('type') # attribute

i error: attributeerror: 'nonetype' object has no attribute 'text'

is there simple way this?

you may try built-in split method:

>>>[data.split('>')[1].split('<')[0] data in str(xml_file).split('<d:') if 'bc_10year' in data][0] '2.16'
