<p>Is there a way to find all nodes in a xml tree using cElementTree? The findall method works only for specified tags.</p>

You can use
XPath paths
on the findall method:
The 1.2 release supports simple
  element location paths. In its
  simplest form, a location path is one
  or more tag names, separated by
  slashes (/).
You can also use an asterisk (*)
  instead of a tag name, to match all
  elements at that level. For example,
  */subtag returns all subtag grandchildren.
An empty tag (//) is used to search on
  all levels of the tree, beneath the
  current level. The empty tag must
  always be followed by a tag name or an
  asterisk.

```
etree.findall('.//*')
