First, the example is not valid xml. You can use xml.etree that comes included:

from xml.etree import ElementTree as et
xmlstr="""\
<?xml version="1.0"?>
<area>
  <media>
    <options>
         <name>Jaipur</name>
    </options>
 </media>
</area>"""
doc=et.fromstring(xmlstr)
doc.find('.//name').text='Mumbai'
print et.tostring(doc)

output:

<area>
  <media>
    <options>
         <name>Mumbai</name>
    </options>
 </media>
</area>
