You might want to add " to your list. And if in the majority of
cases thisText doesn't contain the special characters the following
will be better performance-wise:
def splitLines(thisText):
if thisText == None:
return []
if '&' in thisText: thisText = thisText.replace('&', '&')
if '<' in thisText: thisText = thisText.replace('<', '<')
if '>' in thisText: thisText = thisText.replace('>', '>')
if '"' in thisText: thisText = thisText.replace('"', '"' )
return '<br/>'.join(thisText.split('\n'))
And if this part of your code becomes the real performance bottleneck
you might want to do the search/replace using the re module. Take a
look at xml.etree.ElementTree in the stdlib for an example (if you
have python > 2.4).
