[Tutor] lxml.html

[nitin chandra]

Hello Every One,

         doc = lxml.html.parse('/home/dev/wsgi-scripts/index.py').getroot()
         name = doc.forms[0].fields['name']

         html = 'name is '
         html += name

I am extracting form field name / value from an html, but then it
gives the above error and does
not display the value of the variable 'name' entered in the respective form.

Thank
