Use find() to get the nodes of interest. The text attribute of the node
contains the text. For example:
data = '''<biological_processess>
<biological_process>
Signal transduction
</biological_process>
<biological_process>
Energy process
</biological_process>
</biological_processess>
'''
from elementtree import ElementTree
tree = ElementTree.fromstring(data)
for process in tree.findall('biological_process'):
print process.text.strip()
prints
Signal transduction
Energy process
You will have to modify the path in the findall to match your actual
data, assuming what you have shown is just a snippet.
I stripped whitespace from the text because otherwise it includes the
newlines and indents exactly as in the original.
