with elementtree:
from elementtree import ElementTree as et
tree = et.parse('temp.xml')
company_list = tree.findall('company')
for company in company_list:
if company.attrib['name'] == 'ndtv':
for founder in company.findall('founder'):
for child in founder.getchildren():
print child.tag, child.text
with lxml (note the difference a full xpath implementation makes):
from lxml import etree
tree = etree.parse('temp.xml')
ndtv_founder_list = tree.xpath('[EMAIL PROTECTED]"ndtv"]/founder')
for founder in ndtv_founder_list:
for child in founder.getchildren():
print child.tag, child.text
I'll leave the modifying of tags and the writing of new xml files up
to you. A note on your sample.xml: why is it
<founder>
<one>larry page</one>
<two>sergey brin</two>
</founder>
when it could just be
<founder>larry page</founder>
<founder>sergey brin</founder>
? That would make it easier to parse the text out. (Probably easier
to produce as well.)
