How to retrieve the parent node using cElementTree?

Question

for the xml

  
     data1
  
  
     data2

        

Answer 1

It seems you can get access to the parent from the child using version 1.3 of ElementTree (check http://effbot.org/zone/element-xpath.htm), by using xpath commands like child.find('../parent'). But I think python ships with version 1.2 or something.

You should also check for lxml which is compatible with etree and has full Xpath support http://lxml.de/

Answer 2

This syntax seemed to work for cElementTree

ET.fromstring("<c><a><b></b></a></c>").find('.//b/..')

No going to base parent, and using double slash then single slash in path.

Answer 3

parent_map = dict((c, p) for p in tree.getiterator() for c in p)
parent_map[el].remove(el)
