 This is the proper way to do it (note the dot prefixing the ``.//p`` XPath)::
 
     >>> for p in divs.xpath('.//p'):  # extracts all <p> inside
-    >>>     print p.extract()
+    ...     print p.extract()
 
 Another common case would be to extract all direct ``<p>`` children::

-    >>>     print p.extract()
