Here's the escape sequences for the special characters in XML:
Sequence 	Character
|&lt;| 	|<|
|&gt;| 	|>|
|&quot;| 	|"|
|&amp;| 	|&|

(from software carpentry: http://osl.iu.edu/~lums/swc/www/xml.html )


You can use the re module to replace each character for it's escape 
sequence in your paragraphs:

 >>>string = 'smtih & smith'
 >>>import re

>>>re.sub('&', '&amp;', string)
'smith &amp; smith'
