>>> from Bio import Entrez

>>> handle=Entrez.einfo()

>>> record=Entrez.read(handle)

Traceback (most recent call last):

 File "<stdin>", line 1, in <module>

 File "/usr/local/lib/python2.7/dist-packages/Bio/Entrez/__init__.py", line 372, in read

   record = handler.read(handle)

 File "/usr/local/lib/python2.7/dist-packages/Bio/Entrez/Parser.py", line 197, in read

   raise NotXMLError(e)
