[Tutor] how to extract text by specifying an element using ElementTree

[Srinivas Iyyer]

Hi group,
  I just have another question in parsin XML files. I
found it very easy to parse XML files with kent and
danny's help. 

I realized that all my XML files have '\t' and '\n'
and whitespace.  these extra features are making to
extract the text data from the xml files very
difficult.  I can make these XML parser work when I
rekove '\n' and '\t' from xml files. 

is there a way to get rid of '\n' and '\t' characters
from xml files easily. 
thank you very much.
MDan
