[Tutor] getting text within an element [attribute text] using elementtree

[ps python]

Dear group, 
In my XML file some attributes have text within an
element. I want to get that text. How can I do that. 
I looked into ElementTree -bits and pieces: and there
is a small function. 

>>> def gettext(elem):
...     text = elem.text or ""
...     for e in elem:
...             text += gettext(e)
...             if e.tail:
...                     text += e.tail
...     return text

>>> for m in
tree.findall('//{org:hprd:dtd:hprdr2}proteinInteractor'):
...     k = gettext(m)
...     print k
...
>>>

I got nothing out of it. 

I tried more preliminary way:

>>> for m in
tree.findall('//{org:hprd:dtd:hprdr2}proteinIn
...     k = 
m.findtext('{org:hprd:dtd:hprdr2}secondaryRef'
...     print k
...
>>> for m in
tree.findall('//{org:hprd:dtd:hprdr2}proteinIn
...     print m
...
>>>

The part of the xml file is listd below. 

Could any one you help me please. 

I want to get :
 <proteinInteractor id="HISTONEH3">

id value:

Thanks
